CVE-2026-23208

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a flaw within the ALSA subsystem related to USB audio handling. Specifically, an issue exists where the number of frames calculated for data URBs can exceed the allocated buffer size, leading to an out-of-bounds write condition. This occurs when a user constructs specific parameters, such as a maxpacksize of 40 for a rate of 22050 with a packets configuration resulting in a frame count exceeding the URB buffer size. The issue was identified through kernel address sanitizer (KASAN) testing.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
