Description OSIDB Bzimport 2026-08-15 12:48:08 UTC
In the Linux kernel, the following vulnerability has been resolved:

ALSA: 6fire: Fix UAF at error handling during probe

Although 6fire driver had a few fixes for dealing with the early error
handling during the probe phase, it forgot a pending URB before
freeing the resources, which may lead to a UAF.

This patch addresses it by doing the almost same cleanup procedure
like the normal disconnect phase at the error path.
