Overview

CVE-2026-64485 is a high-severity vulnerability. It was published on July 25, 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: compress: Fix task creation error unwind

snd_compr_task_new() allocates the driver task before validating the

returned DMA buffers and reserving file descriptors. When either of

those later steps fails, the core frees its task wrapper and DMA-buffer

references without calling the driver's task_free() callback. Any

driver resources allocated by task_create() are therefore leaked.

The dual-fd allocation path also jumps to cleanup without storing the

negative get_unused_fd_flags() result in retval. Since retval still

contains the successful task_create() return value, TASK_CREATE can

incorrectly report success although the task was discarded.

Preserve the fd allocation errors and call task_free() when failure

occurs after a successful task_create() callback.

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.

How can CyberStrike help with CVE-2026-64485?

CyberStrike is an open-source, AI-augmented pentesting engine.
