How to fix?

Upgrade Amazon-Linux:2023 kernel-headers to version 0:6.1.124-134.200.amzn2023 or higher.
This issue was patched in ALAS2023-2025-809.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-headers package and not the kernel-headers package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

ftrace: Fix regression with module command in stack_trace_filter

When executing the following command:

# echo &#34;write*:mod:ext3&#34; &gt; /sys/kernel/tracing/stack_trace_filter

The current mod command causes a null pointer dereference. While commit 0f17976568b3f ("ftrace: Fix regression with module command in stack_trace_filter") has addressed part of the issue, it left a corner case unhandled, which still results in a kernel crash.
