CVE-2024-35822

Kernel warning via disabled USB endpoint queue

Published May 17, 2024 · Updated May 11, 2026

Race condition in Linux kernel USB gadget UDC code allows local users to trigger a kernel warning during mass-storage teardown. The mass-storage function's main thread can call usb_ep_queue() after another thread disables the endpoint, causing WARN_ON_ONCE() to emit a warning. The USB mass-storage gadget must be active during concurrent function disable; the kernel record reports no driver failure beyond the diagnostic.
