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

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...
