{"id":"CVE-2026-92497","summary":"wifi: ath12k: Avoid buffer overread in ath12k_wmi_op_rx()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath12k: Avoid buffer overread in ath12k_wmi_op_rx()\n\nCurrently, in ath12k_wmi_op_rx(), the firmware buffer is read without\nfirst verifying that the buffer has enough data to hold a header. This\ncould result in a buffer overread.\n\nUpdate the logic to verify the buffer contains at least enough data to\nhold a wmi_cmd_hdr before reading from the buffer.\n\nTested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c7-00108-QCAHMTSWPL_V1.0_V2.0_SILICONZ_UPSTREAM-3","modified":"2026-09-19T03:47:31.086772313Z","published":"2026-09-17T16:10:12.081Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92497.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/07659388110de004cbb753f3c7bc85e657e51f7a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7698656a2f7b045af5a6859766238cefea1b1945"},{"type":"WEB","url":"https://git.kernel.org/stable/c/95d1bd1db9e9d8eccffc880166e01c4775115716"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9784faa6afd26693287e8e4569bdedee00212909"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9e6ec0977f0b9c16fc20efea050e3eea8f66e34b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92497.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92497"},{"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":"d889913205cf7ebda905b1e62c5867ed4e39f6c2"},{"fixed":"9784faa6afd26693287e8e4569bdedee00212909"},{"fixed":"07659388110de004cbb753f3c7bc85e657e51f7a"},{"fixed":"95d1bd1db9e9d8eccffc880166e01c4775115716"},{"fixed":"9e6ec0977f0b9c16fc20efea050e3eea8f66e34b"},{"fixed":"7698656a2f7b045af5a6859766238cefea1b1945"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92497.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.3.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92497.json"}}],"schema_version":"1.9.0"}
