CVE-2026-80659

A flaw was found in the Linux kernel's vub300 driver. When the vub300cmndworkthread function holds a command mutex and a command response times out, the device reset path attempts to re-acquire the same mutex recursively. This recursive locking can lead to a deadlock, causing a Denial of Service...
