Description OSIDB Bzimport 2025-09-11 17:02:30 UTC
In the Linux kernel, the following vulnerability has been resolved:

ALSA: usb-audio: Validate UAC3 cluster segment descriptors

UAC3 class segment descriptors need to be verified whether their sizes
match with the declared lengths and whether they fit with the
allocated buffer sizes, too.  Otherwise malicious firmware may lead to
the unexpected OOB accesses.
