{"id":"CVE-2026-92496","summary":"wifi: ath11k: Avoid buffer overread in ath11k_wmi_tlv_op_rx()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath11k: Avoid buffer overread in ath11k_wmi_tlv_op_rx()\n\nCurrently, in ath11k_wmi_tlv_op_rx(), the firmware buffer is read\nwithout first verifying that the buffer has enough data to hold a\nheader. This could result in a buffer overread.\n\nAdd an upfront length check before dereferencing skb-\u003edata as a\nwmi_cmd_hdr. The check is placed before the trace_ath11k_wmi_event()\ncall to preserve the existing trace semantics (tracing the full raw\nWMI event including the header), unlike the analogous ath12k fix which\ncould use skb_pull_data() directly.\n\nCompile tested only.","modified":"2026-09-19T03:47:26.495516181Z","published":"2026-09-17T16:10:11.423Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92496.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/20166fd9a4ad15d7eccc63c9dc99680aea6558ef"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2677fc48dd10dc08cdec99c2692d50fe5f48dcbf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/71690d26c1415e816158b45ee354367244c50d4c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/72a5e45f606ec454ef556a68ffd92e06b0677f44"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9652e7e23137538169f60323300cae3413475685"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9ddbc95dac167e3f2d0e3859e6ce022ae0184fc1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9ef9dd30058cc9223c72f711dca1a28a5947d0c5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f9726f6d97dca94ab14739c8b632301a940a7e8f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92496.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92496"},{"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":"d5c65159f2895379e11ca13f62feabe93278985d"},{"fixed":"20166fd9a4ad15d7eccc63c9dc99680aea6558ef"},{"fixed":"71690d26c1415e816158b45ee354367244c50d4c"},{"fixed":"f9726f6d97dca94ab14739c8b632301a940a7e8f"},{"fixed":"2677fc48dd10dc08cdec99c2692d50fe5f48dcbf"},{"fixed":"9652e7e23137538169f60323300cae3413475685"},{"fixed":"72a5e45f606ec454ef556a68ffd92e06b0677f44"},{"fixed":"9ddbc95dac167e3f2d0e3859e6ce022ae0184fc1"},{"fixed":"9ef9dd30058cc9223c72f711dca1a28a5947d0c5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92496.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.6.0"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"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-2026-92496.json"}}],"schema_version":"1.9.0"}
