CVE-2026-46074

Estado: En análisisMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

spi: ch341: fix memory leaks on probe failures

Make sure to deregister the controller, disable pins, and kill and free the RX URB on probe failures to mirror disconnect and avoid memory leaks and use-after-free.

Also add an explicit URB kill on disconnect for symmetry (even if that is not strictly required as USB core would have stopped it in the current setup).
