A vulnerability in the Linux kernel's CAN network subsystem was resolved by restoring skb header initialization in the init_can_skb() function. The issue was introduced when certain skb header reset calls were removed, causing RX skbs to carry an invalid mac_header value. This leads to an overflow in push length calculation in packet_rcv_spkt(), triggering a kernel panic and full machine crash. The problem was originally reported in 2014 and fixed then, but the recent commit reintroduced it. The vulnerability affects kernel stability and can cause denial of service via system crash.
