can: bcm: validate frame length in bcm_rx_setup() for RTR replies
Type: advisorySources: OSV
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.
