A flaw was found in the Linux kernel's USB gadget subsystem (f_tcm). A malicious or misconfigured USB host can exploit a race condition by sending specific Bulk-Only Transport (BOT) commands. This can trigger a NULL pointer dereference, leading to a kernel panic and a local Denial of Service (DoS) on the affected system.
