Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: ext4: fix string copying in
 parse_apply_sb_mount_options() strscpy_pad() can't be used to copy a non-NUL-term string into a NUL-term
 string of possibly bigger size. Commit 0efc5990bca5 ("string.h: Introduce memtostr() and memtostr_pad()")
 provides additional information in that regard. So if this happens, the following warning is observed:
 strnlen: detected buffer overflow: 65 byte read of buffer size 64 WARNING: CPU: 0 PID: 28655 at

 userspace is expected to provide s_mount_opts field to be at most 63 characters long with the ending byte
 being NUL-term, use a 64-byte buffer which matches the size of s_mount_opts, so that strscpy_pad() does
 its job properly. Return with error if the user still managed to provide a non-NUL-term string here. Found
 by Linux Verification Center (linuxtesting.org) with Syzkaller. (CVE-2025-71123)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.294.100 or later.
