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...

CVE-2026-72123

CVE-2026-72123 concerns Linux kernel CAN BCM RX teardown where a race between a concurrent RCU reader and a deferred thrtimer could dereference a freed op, causing a use-after-free. Root cause: after replacing synchronize_rcu() with call_rcu() and introducing RX_NO_AUTOTIMER, the thrtimer path in...

CVE-2026-72121

CVE-2026-72121 describes a Linux kernel CAN subsystem vulnerability in which KCSAN detected a race condition updating timer and filter state during CAN message handling. The fix introduces a per-operation bcm_rx_update_lock to serialize updates to timer values (ival1/ival2/kt_ival1/kt_ival2/kt_la...

CVE-2026-72116

The CVE-2026-72116 entry describes a Linux kernel issue in the CAN networking path (bcm) where stale RX/TX operation references could occur after device removal. RX: an RX_SETUP update could skip can_rx_register() if NETDEV_UNREGISTER occurred, leaving rx_ops with ifindex=0 and not re-enabling fr...
