CVE-2026-72116 can: bcm: fix stale rx/tx ops after device removal

In the Linux kernel, the following vulnerability has been resolved: can: bcm: fix stale rx/tx ops after device removal RX: an RXSETUP update! for an existing op skipped canrxregister unconditionally, even when a concurrent NETDEVUNREGISTER had already torn down its registration op-rxregdev == NUL...

CVE-2026-72117

CVE-2026-72117 concerns the Linux kernel “can: bcm” code, where a data race on rx_stamp/rx_ifindex in bcm_rx_handler() could occur for an rx op subscribed to all interfaces (ifindex == 0). The same op could be registered in a shared per-netns wildcard filter list, allowing concurrent bcm_rx_handl...

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...

CVE-2026-72117 can: bcm: fix data race on rx_stamp/rx_ifindex in bcm_rx_handler()

In the Linux kernel, the following vulnerability has been resolved: can: bcm: fix data race on rxstamp/rxifindex in bcmrxhandler For an rx op subscribed on all interfaces ifindex == 0, the same op is registered once in the shared per-netns wildcard filter list, so bcmrxhandler can run concurrentl...

CVE-2026-72115 can: bcm: track a single source interface for ANYDEV timeout/throttle ops

In the Linux kernel, the following vulnerability has been resolved: can: bcm: track a single source interface for ANYDEV timeout/throttle ops An ANYDEV rx op ifindex == 0 with an active RX timeout and/or throttle timer has no defined semantics when matching frames arrive from several interfaces:...

CVE-2026-72115

The CVE-2026-72115 issue affects the Linux kernel CAN BCM RX path. A race between bcm_rx_handler(), hrtimer_cancel(), bcm_rx_starttimer(), and bcm_rx_timeout_handler() could allow an ANYDEV operation (ifindex == 0) to process frames from multiple interfaces, causing spurious RX_TIMEOUT events and...

CVE-2026-72114 can: bcm: validate frame length in bcm_rx_setup() for RTR replies

In the Linux kernel, the following vulnerability has been resolved: can: bcm: validate frame length in bcmrxsetup for RTR replies bcmtxsetup validates cf-len against the CAN/CAN FD DLC limits before installing frames for TXSETUP, but bcmrxsetup never did the same for the RTR-reply frame configure...

CVE-2026-72114

In the Linux kernel CAN BCM subsystem, CVE-2026-72114 is due to bcm_rx_setup() not validating the frame length for RTR-reply frames configured via RX_SETUP with RX_RTR_FRAME, unlike bcm_tx_setup() which validates cf->len against CAN/CAN FD DLC limits. The vulnerability is resolved by adding va...
