Medium [CVE-2026-72114] validate frame length in bcm_rx_setup for RTR replies
CVE-2026-72114Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: can: bcm: validate frame length in bcm_rx_setup() for RTR replies bcm_tx_setup() validates cf->len against the CAN/CAN FD DLC limits before installing frames for TX_SETUP, but bcm_rx_setup() never did the same for the RTR-reply frame configured via RX_SETUP with RX_RTR_FRAME. A flaw was found in the Linux kernel's Controller Area Network (CAN) Broadcom (bcm) driver. This vulnerability arises from insufficient validation of frame lengths when processing Remote Transmission Request (RTR) replies. An attacker could exploit this by sending a specially crafted RTR reply, which may lead to a system crash or other unpredictable system behavior. Red Hat severity: Moderate — CVSS 5.5…
