## Overview

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 "write*:mod:ext3" > /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.

## Affected

- `linux_kernel >= 4.12, < 5.4.287`
- `linux_kernel >= 5.5, < 5.10.231`
- `linux_kernel >= 5.11, < 5.15.174`
- `linux_kernel >= 5.16, < 6.1.120`
- `linux_kernel >= 6.2, < 6.6.64`
- `linux_kernel >= 6.7, < 6.12.4`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.12.4`
