Google: sys-kernel/cchost-kernel-6_12, sys-kernel/csql-kernel-6_12, sys-kernel/lakitu-kernel-6_12, sys-kernel/lakitu-nc-kernel-6_12: security update to 19506.299.116

high Tenable Self-Hosted Container Security Plugin ID 469487

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: proc: protect ptrace_may_access() with
exec_update_lock (FD links) proc_pid_get_link() and proc_pid_readlink() currently look up the task from
the pid once, then do the ptrace access check on that task, then look up the task from the pid a second
time to do the actual access. That's racy in several ways. To fix it, pass the task to the
->proc_get_link() handler, and instead of proc_fd_access_allowed(), introduce a new helper
call_proc_get_link() that looks up and locks the task, does the access check, and calls ->proc_get_link().
(CVE-2026-64375)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.299.116 or later.
