CVE-2025-39986

The CVE-2025-39986 entry concerns the sun4i_can driver in the Linux kernel. The root cause is that sun4i_can does not populate net_device_ops->ndo_change_mtu(), which allows a local attacker to set an invalid MTU (e.g., mtu 9999) via PF_PACKET and then inject CAN XL frames through ETH_P_CANXL....
