{"id":"CVE-2026-98159","summary":"wifi: mt76: mt7921: validate CLC firmware records","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7921: validate CLC firmware records\n\nThe CLC region is supplied by firmware, but the loader trusts the\nregion count and each record length. A malformed image can make the\nregion table pointer precede the firmware buffer, make the record loop\nfail to advance, or index phy-\u003eclc past its end. Validate the table and\nrecord bounds before dereferencing or copying.","modified":"2026-09-26T03:48:37.467587494Z","published":"2026-09-25T10:36:28.206Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98159.json","cna_assigner":"Linux"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3896be051e928c891922d91de94c99519d215dff"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3c505e2af16a9320f4355218394a955fbbc65322"},{"type":"WEB","url":"https://git.kernel.org/stable/c/602a950134ee2940136f60797e4457c3983b06ce"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9417c5818a0146980c2608fda94c908e604eb033"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98159.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98159"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"23bdc5d8cadfc941e7782d0cb8afb2d9ae73b125"},{"fixed":"602a950134ee2940136f60797e4457c3983b06ce"},{"fixed":"3896be051e928c891922d91de94c99519d215dff"},{"fixed":"3c505e2af16a9320f4355218394a955fbbc65322"},{"fixed":"9417c5818a0146980c2608fda94c908e604eb033"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98159.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98159.json"}}],"schema_version":"1.9.0"}
