CVE-2024-56569: ftrace: Fix regression with module command in stack_trace_filter
In the Linux kernel, the following vulnerability has been resolved:
ftrace: Fix regression with module command in stacktracefilter
When executing the following command:
# echo "write:mod:ext3" > /sys/kernel/tracing/stacktracefilter
The current mod command causes a null pointer dereference. While commit 0f17976568b3f ("ftrace: Fix regression with module command in stacktracefilter") has addressed part of the issue, it left a corner case unhandled, which still results in a kernel crash.
