CVE-2026-72114
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…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.16%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
