Fixes a sandbox escape through symlink traversal tracked in
CVE-2026-87766, which affects all previous versions.
Using the bwrap binary with the setuid bit set is no longer supported
and user namespaces are now always required, so a kernel config fixup
is applied.
A new build option allows indicating the minimum kernel version that
will be used, which removes code used for backwards compatibility with
kernels older than 5.6.0 when a newer version is specified. Passing
$(LINUX_VERSION_PROBED) seems reasonable here.
This version also changed the license from LGPL-2.0+ to LGPL-2.1+,
hence the updated hash.

To indicate that a patch fixes a vulnerability in Buildroot, the convention is:
1. In the patch file, add a tag 'CVE: <cve id>'
2. In <pkg>.mk, and an entry to <PKG>_IGNORE_CVES, and add a comment above
that new entry to reference the patch file(s)
However, as packages get bumped and their patches are added, removed or
rebased; it happens that IGNORE_CVES get outdated. One important issue is
marking a CVE as ignored, while the corresponding patch is not in Buildroot.
To detect such cases, add a new checker to checkpackagelib that finds
occurences of:
# 000x-some-patch.patch
PKG_IGNORE_CVES += CVE-XXXX-YYYY
For each one of them, ensure that the mentioned patch files actually exist
and contain the `CVE: ...` tag.

Fixes the following security issues:
(Security fix for specific API usage, GHSA-2p8c-ff85-vh9x)
If pcre2_jit_compile() is called with options for some match modes, and
then pcre2_match() is used to perform a match for a different match
mode, an out-of-bounds read can occur if the match is attempted against
invalid UTF input.
(Security fix for pattern conversion, GHSA-q8g2-wprr-34m9)
If pcre2_convert() is called on untrusted input on platforms with
32-bit size_t, an out-of-bounds heap write can occur.
(Security fix, GHSA-3r4p-g7gg-ppmf) Fixed an out-of-bounds write in DFA
matching when using a heap limit; also fixed possible integer overflows
which could cause under-allocation of the workspace.
(Security fix, GHSA-fmgr-6ggq-9859) Added bounds checks for several
integer overflows while compiling patterns on 32-bit CPUs, which could
cause under-allocation followed by out-of-bounds writes.
(Security fix, GHSA-9qww-pwc4-77qq) Applied lower buffer bound to
prevent two out-of-bounds reads while scanning backwards through
invalid UTF data with PCRE2_MATCH_INVALID_UTF.
(Security fix for specific API usage, #937) Fixed a leak and later
invalid free when calling the fast-path pcre2_jit_match() function with
a match data object previously used with pcre2_match() and
PCRE2_COPY_MATCHED_SUBJECT.

Security fixes:
HTTP header injection: header values were only checked for a literal
\r\n, so a lone \r or \n could still split a header. Now rejected on
either character.
Transfer-Encoding requests are now rejected with 501 instead of silently
mishandled, closing a request smuggling avenue.
A real default request body size cap (128 MB) with a 413 response,
previously unbounded.
Secure cookie signature now binds the cookie name, so a value signed for
one cookie can no longer be replayed under a different name.
Verification failures return the default value instead of raising.
Constant-time comparison for the secure cookie HMAC, previously a
timing-leaky ==.
util.secure_random_bytes reads real OS entropy (/dev/urandom,
BCryptGenRandom on Windows) for WebSocket masks and util.rand_str,
previously math.random.
WebSocket: unmasked client frames are rejected per RFC 6455, and
fragmented message reassembly is capped to max_buffer_size to close a

This fixes the following vulnerabilities:
- CVE-2026-21620:
Relative Path Traversal, Improper Isolation or Compartmentalization
vulnerability in erlang otp erlang/otp (tftp_file modules), erlang otp
inets (tftp_file modules), erlang otp tftp (tftp_file modules) allows
Relative Path Traversal. This vulnerability is associated with program
files lib/tftp/src/tftp_file.erl, src/tftp_file.erl.
For more information, see:
- https://www.cve.org/CVERecord?id=CVE-2026-21620
- CVE-2026-23941:
Inconsistent Interpretation of HTTP Requests ('HTTP Request
Smuggling') vulnerability in Erlang OTP (inets httpd module) allows
HTTP Request Smuggling. This vulnerability is associated with program
files lib/inets/src/http_server/httpd_request.erl and program routines
httpd_request:parse_headers/7. The server does not reject or
normalize duplicate Content-Length headers. The earliest Content-
Length in the request is used for body parsing while common reverse
proxies (nginx, Apache httpd, Envoy) honor the last Content-Length
value. This violates RFC 9112 Section 6.3 and allows front-end/back-
end desynchronization, leaving attacker-controlled bytes queued as the
start of the next request.
For more information, see:
- https://www.cve.org/CVERecord?id=CVE-2026-23941
- CVE-2026-23942:
Improper Limitation of a Pathname to a Restricted Directory ('Path
Traversal') vulnerability in Erlang OTP (ssh_sftpd module) allows Path
Traversal. This vulnerability is associated with program files
lib/ssh/src/ssh_sftpd.erl and program routines
ssh_sftpd:is_within_root/2. The SFTP server uses string prefix
matching via lists:prefix/2 rather than proper path component
validation when checking if a path is within the configured root
directory. This allows authenticated users to access sibling
directories that share a common name prefix with the configured root
directory. For example, if root is set to /home/user1, paths like
/home/user10 or /home/user1_backup would incorrectly be considered
within the root.
For more information, see:
- https://www.cve.org/CVERecord?id=CVE-2026-23942
- CVE-2026-23943:
Improper Handling of Highly Compressed Data (Compression Bomb)
vulnerability in Erlang OTP ssh (ssh_transport modules) allows Denial
of Service via Resource Depletion. The SSH transport layer advertises
legacy zlib compression by default and inflates attacker-controlled
payloads pre-authentication without any size limit, enabling reliable
memory exhaustion DoS. Two compression algorithms are affected: *
zlib: Activates immediately after key exchange, enabling
unauthenticated attacks * zlib@openssh.com: Activates post-
authentication, enabling authenticated attacks Each SSH packet can
decompress ~255 MB from 256 KB of wire data (1029:1 amplification
ratio). Multiple packets can rapidly exhaust available memory, causing
OOM kills in memory-constrained environments. This vulnerability is
associated with program files lib/ssh/src/ssh_transport.erl and
program routines ssh_transport:decompress/2,
ssh_transport:handle_packet_part/4.
For more information, see:
- https://www.cve.org/CVERecord?id=CVE-2026-23943
- CVE-2026-28810:
Generation of Predictable Numbers or Identifiers vulnerability in
Erlang/OTP kernel (inet_res, inet_db modules) allows DNS Cache
Poisoning. The built-in DNS resolver (inet_res) uses a sequential,
process-global 16-bit transaction ID for UDP queries and does not
implement source port randomization. Response validation relies almost
entirely on this ID, making DNS cache poisoning practical for an
attacker who can observe one query or predict the next ID. This
conflicts with RFC 5452 recommendations for mitigating forged DNS
answers. inet_res is intended for use in trusted network environments
and with trusted recursive resolvers. Earlier documentation did not
clearly state this deployment assumption, which could lead users to
deploy the resolver in environments where spoofed DNS responses are
possible. This vulnerability is associated with program files
lib/kernel/src/inet_db.erl and lib/kernel/src/inet_res.erl.
For more information, see:
- https://www.cve.org/CVERecord?id=CVE-2026-28810
- CVE-2026-32147:
Improper Limitation of a Pathname to a Restricted Directory ('Path
Traversal') vulnerability in Erlang OTP ssh (ssh_sftpd module) allows
an authenticated SFTP user to modify file attributes outside the
configured chroot directory. The SFTP daemon (ssh_sftpd) stores the
raw, user-supplied path in file handles instead of the chroot-resolved
path. When SSH_FXP_FSETSTAT is issued on such a handle, file
attributes (permissions, ownership, timestamps) are modified on the
real filesystem path, bypassing the root directory boundary entirely.
Any authenticated SFTP user on a server configured with the root
option can modify file attributes of files outside the intended chroot
boundary. The prerequisite is that a target file must exist on the
real filesystem at the same relative path. Note that this
vulnerability only allows modification of file attributes; file
contents cannot be read or altered through this attack vector. If the
SSH daemon runs as root, this enables direct privilege escalation: an
attacker can set the setuid bit on any binary, change ownership of
sensitive files, or make system configuration world-writable. This
vulnerability is associated with program files
lib/ssh/src/ssh_sftpd.erl and program routines ssh_sftpd:do_open/4 and
ssh_sftpd:handle_op/4.
For more information, see:
- https://www.cve.org/CVERecord?id=CVE-2026-32147
- CVE-2026-42789:
Improper Following of a Certificate's Chain of Trust vulnerability in
Erlang OTP public_key (pubkey_cert module) allows a non-CA certificate
to be accepted as an intermediate issuer, enabling certificate chain
forgery. In lib/public_key/src/pubkey_cert.erl,
pubkey_cert:validate_extensions/7 contains two flaws that together
allow a certificate with basicConstraints cA:false and no keyUsage
extension to be used as an intermediate issuer in a chain passed to
public_key:pkix_path_validation/3: the cA:false clause recurses into
the remaining extensions without rejecting the certificate when it is
in issuer position, and the keyUsage check only fires when the
extension is present, so a certificate lacking keyUsage entirely
bypasses the keyCertSign enforcement. Any party holding an end-entity
certificate with basicConstraints cA:false and no keyUsage extension,
issued by any CA in the victim's trust store, can use that
certificate's private key to sign forged leaf certificates for
arbitrary identities. public_key:pkix_path_validation/3 accepts the
resulting chain, and by extension every TLS or mTLS endpoint built on
the OTP ssl application that relies on the default verifier is
affected, including server identity verification on the client side
and client certificate verification on mTLS servers.
For more information, see:
- https://www.cve.org/CVERecord?id=CVE-2026-42789
- CVE-2026-42790:
Improper Certificate Validation vulnerability in Erlang OTP public_key
(pubkey_cert and public_key modules) allows a DNS nameConstraints
bypass via subject CommonName fallback in TLS hostname verification.
Two flaws combine to allow a subordinate CA whose DNS nameConstraints
are restricted (e.g. permitted;DNS:allowed.example.com) to issue a
leaf certificate that an OTP TLS client accepts as a valid identity
for an out-of-scope hostname (e.g. victim.example.com): First,
pubkey_cert:validate_names/6 in lib/public_key/src/pubkey_cert.erl
only checks SAN DNS entries against nameConstraints. Per RFC 5280, a
permitted DNS subtree only restricts certificates that contain a DNS-
typed name. A leaf with no subjectAltName therefore trivially
satisfies any permitted;DNS:... constraint regardless of its subject
commonName. Second, public_key:pkix_verify_hostname/3 in
lib/public_key/src/public_key.erl falls back to the subject commonName
when no subjectAltName is present, extracting id-at-commonName
attributes as presented IDs and matching them against the reference
hostname. The strict pkix_verify_hostname_match_fun(https) matcher
does not suppress this fallback. The result is that path validation
accepts a CN-only leaf under a DNS-constrained intermediate (no SAN
means the nameConstraints are not triggered), and hostname
verification then accepts it via the CN fallback. The bypass is
reachable from stock ssl:connect with verify_peer, a trusted CA, SNI,
and the canonical strict https hostname matcher.

Although OpenSSL was found using pkg-config the build tests fail.
A local build shows the concrete error in config.log, for example:

The build error can be reproduced with the current buildroot tree using
this defconfig:
BR2_m68k=y
BR2_m68k_cf5208=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_M68K_COLDFIRE_UCLIBC_STABLE=y
BR2_PACKAGE_OPENSSL=y
BR2_PACKAGE_LIBCURL=y
Although the toolchain lacks atomics support
$ grep ATOMIC .config
$
it emits atomic-related defines, for example:
$ echo | output/host/bin/m68k-linux-gcc -dM -E - | grep __ATOMIC_ACQ_REL
#define __ATOMIC_ACQ_REL 4
$
This specific define __ATOMIC_ACQ_REL is used in OpenSSL to enable
atomic support at various places:
https://github.com/openssl/openssl/blob/openssl-3.6.3/crypto/threads_pthread.c
causing the build errors we see with the mentioned defconfig.
To fix the problem we use an OpenSSL-provided define to forcefully
disable the usage of atomic intrinsics.
The misdetection of atomic intrinsics for m68k coldfire is not a new
problem:

The mdnsd runtime test can randomly fail on slow runners.
It's hard to reproduce locally (only one failure after a few attempts)
but we can reproduce it easily by removing the while loop entirely.
It turns out that mdnsd is started by S50mdnsd before the
emulator.login() change the system date:
[BRTEST# date -s @1788032864
Sat Aug 29 19:47:44 UTC 2026
Since the minimal rootfs.cpio generated for TestMdnsd doesn't have any
ntp client installed, it start with "January 1, 1970".
The date change may cause some issue to the mdnsd daemon which blocks
any response from mquery command.
When the problem occurs, "mquery -T _http._tcp" reply is empty:
# mquery -T _http._tcp
Querying _http._tcp.local. for PTR (12) ... press Ctrl-C to stop
To workaround the issue, restart mdnsd manually.

Dracut-internal executables were linked against system libraries,

libzstd.so.1 => /usr/lib/x86_64-linux-gnu/libzstd.so.1 (0x00007f578c536000)
The reason is that Dracut is not a "real" autoconf package, and the
hand-written ./configure script does not preserve LDFLAGS for
make. Pass the environment variables directly to fix this.

examples/vm_power_manager/meson.build in DPDK detects the presence of
libvirt:
opt_dep = cc.find_library('virt', required : false)
and then builds some examples or not depending on the availability of
libvirt. Let's make this optional dependency explicit in dpdk.mk, even
if there's no explicit enable/disable option for it.

When libvirt is present before DPDK is built, some additional examples
are compiled. One of them fails to build due to a missing <stdlib.h>
include. Let's import a patch from OpenSuse, that we have submitted
upstream, to fix this issue.
We couldn't find any autobuilder failure for this issue, but the
following defconfig allows to reproduce the failure:
BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_AARCH64_GLIBC_STABLE=y
BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y
BR2_PACKAGE_DPDK=y
BR2_PACKAGE_DPDK_EXAMPLES=y
BR2_PACKAGE_LIBVIRT=y
The problem exists since DPDK v19.11, so it has been in Buildroot
since DPDK was introduced in commit
d17d1b6bde.

Buildroot commit [1] (package/perl: fix build issue with musl)
introduced a patch that is meant to be applied on top of perl-cross,
which is extracted on top of perl only in the target variant.
Since the patch was introduced as a normal package patch, the Buildroot
infra is trying to always apply it, even for the host package variant.
Since perl-cross is not extracted for the host variant, some patched
files are missing. In that case, the host-perl is failing with error:
>>> host-perl 5.42.3 Patching
Applying 0001-configure-keep-_GNU_SOURCE-in-build-flags.patch using patch:
can't find file to patch at input line 46
This commit fixes the issue by moving the package patch in a dedicated
"perl-cross" subdirectory, to make sure it will no longer be applied by
the infra. We apply the patch only for the target package variant using
a _POST_PATCH_HOOKS hook.
Fixes:
- [1]
- https://gitlab.com/buildroot.org/buildroot/-/jobs/16185948610 (TestPerlXMLLibXML)
- ...and few other tests requiring host-perl

When OpenSSL is enabled, if DES support is enabled, OpenSSH uses
DES_crypt. However, without OpenSSL or its DES support, there is no
available crypt() implementation for OpenSSH libopenbsd-compat xcrypt()

This commit enables BR2_PACKAGE_LIBXCRYPT with OpenSSH as long as
glibc is used. Since "sshd-auth" is compiled regardless of
BR2_PACKAGE_OPENSSH_SERVER, we need to enable it with BR2_PACKAGE_OPENSSH.
