Google: sys-kernel/csql-kernel-6_1, sys-kernel/lakitu-kernel-6_1: security update to 18244.448.50

high Tenable Self-Hosted Container Security Plugin ID 450993

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: ftrace: Also allocate and copy hash
for reading of filter files Currently the reader of set_ftrace_filter and set_ftrace_notrace just adds the
pointer to the global tracer hash to its iterator. Unlike the writer that allocates a copy of the hash,
the reader keeps the pointer to the filter hashes. This is problematic because this pointer is static
across function calls that release the locks that can update the global tracer hashes. This can cause UAF
and similar bugs. Allocate and copy the hash for reading the filter files like it is done for the writers.
This not only fixes UAF bugs, but also makes the code a bit simpler as it doesn't have to differentiate
when to free the iterator's hash between writers and readers. (CVE-2025-39689)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18244.448.50 or later.
