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.\n\n## Affected\n\n- `Linux >= ef6980b6becb1afd9d82a4f043749a10ae81bf14 < 70013f9163bef7fbd9fa62f81cf91b2a7ba66163`\n- `Linux >= ef6980b6becb1afd9d82a4f043749a10ae81bf14 < be272e159dfe1207b67332ad6e17adcf59b4ea4b`\n- `Linux >= ef6980b6becb1afd9d82a4f043749a10ae81bf14 < 8c8818e52fddb247ff3214622401a4de6ff8482e`\n- `Linux >= ef6980b6becb1afd9d82a4f043749a10ae81bf14 < 9433578bff9c100c466a6354574892e55293cb8f`\n- `Linux >= ef6980b6becb1afd9d82a4f043749a10ae81bf14 < 1cb42ec10294a55380e52e674b3df2b962648242`\n- `Linux >= ef6980b6becb1afd9d82a4f043749a10ae81bf14 < 5526d1997aea6c9bd865ca4d4894b52e799d735c`\n- `Linux >= ef6980b6becb1afd9d82a4f043749a10ae81bf14 < b69ad768cd4a2ef4e07c18492ae85438ed17c7cb`\n- `Linux >= ef6980b6becb1afd9d82a4f043749a10ae81bf14 < 9406f6012b7343661efb516a11c62d4db2b62f75`\n- `Linux 4.6`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":50,"depthScoreParts":{"impact":50.1,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
