Overview

CVE-2022-49288 is a high-severity vulnerability. It was published on February 26, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

ALSA: pcm: Fix races among concurrent prealloc proc writes

We have no protection against concurrent PCM buffer preallocation

changes via proc files, and it may potentially lead to UAF or some

weird problem. This patch applies the PCM open_mutex to the proc

write operation for avoiding the racy proc writes and the PCM stream

open (and further operations).

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
