Overview

CVE-2025-38078 is a high-severity vulnerability. It was published on June 18, 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 race of buffer access at PCM OSS layer

The PCM OSS layer tries to clear the buffer with the silence data at

initialization (or reconfiguration) of a stream with the explicit call

of snd_pcm_format_set_silence() with runtime->dma_area. But this may

lead to a UAF because the accessed runtime->dma_area might be freed

concurrently, as it's performed outside the PCM ops.

For avoiding it, move the code into the PCM core and perform it inside

the buffer access lock, so that it won't be changed during the

operation.

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.
