A truncated file can make the driver\nread beyond the firmware buffer during variant validation or the\nfallback copy.\n\nReject files shorter than MT7996_EEPROM_SIZE before parsing or\ncopying the firmware.","modified":"2026-09-13T03:46:49.254734580Z","published":"2026-09-11T19:42:07.754Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80933.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/03b81f015dbb29807ce1ec6d45537d658abdac69"},{"type":"WEB","url":"https://git.kernel.org/stable/c/653c6e289b13cc6942f3e8f8e3c568e70fa42d1f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7074ec3769820302f1ccf8794a40a6582153b820"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/80xxx/CVE-2026-80933.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-80933"},{"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":"98686cd21624c75a043e96812beadddf4f6f48e5"},{"fixed":"03b81f015dbb29807ce1ec6d45537d658abdac69"},{"fixed":"7074ec3769820302f1ccf8794a40a6582153b820"},{"fixed":"653c6e289b13cc6942f3e8f8e3c568e70fa42d1f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80933.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.18.50"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-80933.json"}}],"schema_version":"1.9.0"}
