Fixes the following security issues:
1) CVE-2025-62229: Use-after-free in XPresentNotify structures creation
Using the X11 Present extension, when processing and adding the
notifications after presenting a pixmap, if an error occurs, a dangling
pointer may be left in the error code path of the function causing a
use-after-free when eventually destroying the notification structures
later.
Introduced in: Xorg 1.15
Fixed in: xorg-server-21.1.19 and xwayland-24.1.9
Fix: https://gitlab.freedesktop.org/xorg/xserver/-/commit/5a4286b1
Found by: Jan-Niklas Sohn working with Trend Micro Zero Day Initiative.
2) CVE-2025-62230: Use-after-free in Xkb client resource removal
When removing the Xkb resources for a client, the function
XkbRemoveResourceClient() will free the XkbInterest data associated
with the device, but not the resource associated with it.
As a result, when the client terminates, the resource delete function
triggers a use-after-free.
Introduced in: X11R6
Fixed in: xorg-server-21.1.19 and xwayland-24.1.9
Fix: https://gitlab.freedesktop.org/xorg/xserver/-/commit/99790a2c

3) CVE-2025-62231: Value overflow in Xkb extension XkbSetCompatMap()
The XkbCompatMap structure stores some of its values using an unsigned
short, but fails to check whether the sum of the input data might
overflow the maximum unsigned short value.
Introduced in: X11R6
Fixed in: xorg-server-21.1.19 and xwayland-24.1.9

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 http://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.
