Description OSIDB Bzimport 2025-12-16 16:01:58 UTC
In the Linux kernel, the following vulnerability has been resolved:

most: usb: fix double free on late probe failure

The MOST subsystem has a non-standard registration function which frees
the interface on registration failures and on deregistration.

This unsurprisingly leads to bugs in the MOST drivers, and a couple of
recent changes turned a reference underflow and use-after-free in the
USB driver into several double free and a use-after-free on late probe
failures.
