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.
A flaw was found in the ALSA 6fire driver within the Linux kernel. During error handling in the probe phase, the driver failed to properly manage a pending USB Request Block (URB) before freeing associated resources. This oversight could lead to a Use-After-Free (UAF) vulnerability. A local attacker could potentially exploit this to cause a system crash (denial of service) or, in some scenarios, execute arbitrary code.
