See the release notes: https://www.samba.org/samba/history/samba-4.22.11.html
This is a security release in order to address the following defects:
o CVE-2026-6949: TSIG packet with name compression can crash DNS
Incorrect size calculations when a TSIG record contains
compressed names can lead to a large out-of-bounds write
causing the server to crash.
https://www.samba.org/samba/security/CVE-2026-6949.html
o CVE-2026-58216: An authenticated user could possibly crash a KDC process
A kpasswd packet that contains malformed ASN.1 might cause
the server to access 6 bytes of unallocated memory. This
memory is not exposed to the user, but in some
circumstances the server could crash.
https://www.samba.org/samba/security/CVE-2026-58216.html
o CVE-2026-58218: DNS signing DoS via TKEY name cache exhaustion
An unauthenticated user can repeatedly register names TKEY
names, which floods a cache causing legitimate TKEYs to be
expunged. This can practically block the use DNS TSIG
signing.
https://www.samba.org/samba/security/CVE-2026-58218.html
o CVE-2026-58221: Samba AD authenticated LDAP access domain takeover
Samba AD low-privilege authenticated LDAP access allows
modifications to internal LDB special DNs, which permits a
domain takeover.
https://www.samba.org/samba/security/CVE-2026-58221.html
o CVE-2026-58222: Samba AD LDAP Compare filter injection and trusted-request
confusion disclose protected attributes
An ordinary authenticated domain user can bypass access
checks and query confidential Active Directory attributes
(such as KDS root keys) via LDAP Compare requests. Due to a
filter injection flaw and trusted execution context, the
LDAP Compare operation can be turned into a
protected-attribute disclosure oracle.
https://www.samba.org/samba/security/CVE-2026-58222.html
o CVE-2026-58224 The CTDB protocol has bounds checking issues
CTDB fails to do integrity checking of received packets.
This includes failure to check field lengths against packet
lengths when unmarshalling packets.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at https://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
