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.","published":"2026-08-15T05:55:17.250Z","modified":"2026-08-18T03:56:23.088496692Z","cvss":{"score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"5.10.261"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1cb42ec10294a55380e52e674b3df2b962648242"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5526d1997aea6c9bd865ca4d4894b52e799d735c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/70013f9163bef7fbd9fa62f81cf91b2a7ba66163"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8c8818e52fddb247ff3214622401a4de6ff8482e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9406f6012b7343661efb516a11c62d4db2b62f75"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9433578bff9c100c466a6354574892e55293cb8f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b69ad768cd4a2ef4e07c18492ae85438ed17c7cb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/be272e159dfe1207b67332ad6e17adcf59b4ea4b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72296.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72296"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T03:56:23.088496692Z"}}
