CVE-2026-72124

A flaw was found in the Linux kernel's Controller Area Network CAN ISO-TP transport protocol module. A race condition in the transmit TX state machine allows for unsynchronized state transitions. This can lead to a situation where a frame or timer callback operates on an outdated state, resulting...

CVE-2026-72124

Summary: CVE-2026-72124 affects the Linux kernel CAN isotp TX state machine. The bug arose from mixing a lock-free cmpxchg() claim in sendmsg() with hrtimer_cancel() under so->rx_lock, creating windows where a frame or timer callback could operate on a migrated TX state and corrupt an unrelate...
