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.","state":0,"publishedAt":"2026-08-15T05:55:17.25+00:00","modifiedAt":"2026-10-16T18:55:15.361+00:00","affected":[{"ecosystem":"Vendor
