{"id":"CVE-2026-72296","summary":"net: ife: require ETH_HLEN to be pullable in ife_decode()","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.","modified":"2026-08-18T03:56:23.088496692Z","published":"2026-08-15T05:55:17.250Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72296.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ef6980b6becb1afd9d82a4f043749a10ae81bf14"},{"fixed":"70013f9163bef7fbd9fa62f81cf91b2a7ba66163"},{"fixed":"be272e159dfe1207b67332ad6e17adcf59b4ea4b"},{"fixed":"8c8818e52fddb247ff3214622401a4de6ff8482e"},{"fixed":"9433578bff9c100c466a6354574892e55293cb8f"},{"fixed":"1cb42ec10294a55380e52e674b3df2b962648242"},{"fixed":"5526d1997aea6c9bd865ca4d4894b52e799d735c"},{"fixed":"b69ad768cd4a2ef4e07c18492ae85438ed17c7cb"},{"fixed":"9406f6012b7343661efb516a11c62d4db2b62f75"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72296.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.6.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72296.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
