CVE-2024-44954

MediumCVSS 4.7/10Last modified Aug 4, 2026

Description

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

ALSA: line6: Fix racy access to midibuf

There can be concurrent accesses to line6 midibuf from both the URB completion callback and the rawmidi API access. This could be a cause of KMSAN warning triggered by syzkaller below (so put as reported-by here).

This patch protects the midibuf call of the former code path with a spinlock for avoiding the possible races.
