CVE-2026-72121

A flaw was found in the Linux kernel's Controller Area Network CAN Broadcom bcm driver. A race condition exists when the driver attempts to update filter and timer values simultaneously with ongoing receive operations. This can lead to the transmission of stale CAN reply frames with an incorrect...

CVE-2026-73523

COVESA Open1722 through 0.9.2 contains an integer truncation vulnerability in acf-can-listener.c that allows unauthenticated remote attackers to cause the CAN listener to transmit process stack memory onto the CAN bus by sending a rejected UDP datagram with a matching AVTP stream ID. The numcanms...
