Overview

CVE-2026-46157 is a high-severity vulnerability. It was published on May 28, 2026 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: oss: Fix data race at accessing runtime.oss.trigger

Currently the runtime.oss.trigger field may be accessed concurrently

without protection, which may lead to the data race. And, in this

case, it may lead to more severe problem because it's a bit field; as

writing the data, it may overwrite other bit fields as well, which

confuses the operation completely, as spotted by fuzzing.

Fix it by covering runtime.oss.trigger bit fled also with the existing

params_lock mutex in both snd_pcm_oss_get_trigger() and

snd_pcm_oss_poll().

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.
