  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ife: require ETH_HLEN to be pullable in ife_decode()\n\nife decode may return after making only the outer IFE header and\nmetadata pullable. The caller then passes the decapsulated packet to\neth_type_trans(), which expects the inner Ethernet header to be\naccessible from the linear data area.\n\nWith a malformed IFE frame, the inner Ethernet header may still be\nshorter than ETH_HLEN in the linear area, which can lead to a crash in\nthe original code.\n\nFix this by extending the pull check in ife_decode() so that the inner\nEthernet header is also guaranteed to be pullable before returning.",
