Overview

CVE-2026-46018 is a medium-severity vulnerability. It was published on May 27, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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: usb-audio: stop parsing UAC2 rates at MAX_NR_RATES

parse_uac2_sample_rate_range() caps the number of enumerated

rates at MAX_NR_RATES, but it only breaks out of the current

rate loop. A malformed UAC2 RANGE response with additional

triplets continues parsing the remaining triplets and repeatedly

prints "invalid uac2 rates" while probe still holds

register_mutex.

Stop the whole parse once the cap is reached and return the

number of rates collected so far.

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-2026-46018?

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