Google: sys-kernel/lakitu-kernel-6_1: security update to 17872.0.0

high Tenable Self-Hosted Container Security Plugin ID 451826

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 swap cpu_buffer
during resize process When ring_buffer_swap_cpu was called during resize process, the cpu buffer was
swapped in the middle, resulting in incorrect state. Continuing to run in the wrong state will result in
oops. This issue can be easily reproduced using the following two scripts: /tmp # cat test1.sh //#!
/bin/sh for i in `seq 0 100000` do echo 2000 > /sys/kernel/debug/tracing/buffer_size_kb sleep 0.5 echo
5000 > /sys/kernel/debug/tracing/buffer_size_kb sleep 0.5 done /tmp # cat test2.sh //#! /bin/sh for i in
`seq 0 100000` do echo irqsoff > /sys/kernel/debug/tracing/current_tracer sleep 1 echo nop >
/sys/kernel/debug/tracing/current_tracer sleep 1 done /tmp # ./test1.sh & /tmp # ./test2.sh & A typical
oops log is as follows, sometimes with other different oops logs. [ 231.711293] WARNING: CPU: 0 PID: 9 at
