Description
In the Linux kernel, the following vulnerability has been resolved: net: ife: require ETH_HLEN to be pullable in ife_decode() ife decode may return after making only the outer IFE header and metadata pullable. The caller then passes the decapsulated packet to eth_type_trans(), which expects the inner Ethernet header to be accessible from the linear data area. With a malformed IFE frame, the inner Ethernet header may still be shorter than ETH_HLEN in the linear area, which can lead to a crash in the original code. Fix this by extending the pull check in ife_decode() so that the inner Ethernet header is also guaranteed to be pullable before returning.
