Description

This security bulletin contains information about 1 vulnerability.


1) Improper handling of exceptional conditions (CVE-ID: CVE-2026-80828)

CWE-ID: CWE-755 - Improper Handling of Exceptional Conditions

CVSSv4: 2.4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows an attacker with physical access to cause a denial of service.

The vulnerability exists due to improper handling of exceptional conditions in the ALSA USB-audio usb_audio_resume() function when processing system-resume failures. An attacker with physical access can trigger a system resume while a USB audio component resume operation fails to cause a denial of service.

The condition applies to system-resume errors; runtime-resume errors follow a distinct error path.
