Google: sys-kernel/lakitu-kernel-6_1: security update to 18026.0.0

high Tenable Self-Hosted Container Security Plugin ID 450496

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: ring-buffer: Do not attempt to read
past "commit" When iterating over the ring buffer while the ring buffer is active, the writer can corrupt
the reader. There's barriers to help detect this and handle it, but that code missed the case where the
last event was at the very end of the page and has only 4 bytes left. The checks to detect the corruption
by the writer to reads needs to see the length of the event. If the length in the first 4 bytes is zero
then the length is stored in the second 4 bytes. But if the writer is in the process of updating that
code, there's a small window where the length in the first 4 bytes could be zero even though the length is
only 4 bytes. That will cause rb_event_length() to read the next 4 bytes which could happen to be off the
allocated page. To protect against this, fail immediately if the next event pointer is less than 8 bytes
from the end of the commit (last byte of data), as all events must be a minimum of 8 bytes anyway.
(CVE-2023-52501)
