{"id":"CVE-2026-90354","summary":"wifi: mt76: mt7915: fix double hif2 init on the non-WED path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7915: fix double hif2 init on the non-WED path\n\nmt7915_pci_init_hif2() was called unconditionally and again inside the\nWED-inactive branch. The helper increments the global hif_idx, writes the\nPCIe RECOG_ID register and takes a get_device() reference via\nmt7915_pci_get_hif2(), while removal only drops one reference. On non-WED\ndual-hif hardware this double-incremented hif_idx, wrote RECOG_ID twice and\nleaked a device reference. Only the call inside the WED-inactive branch is\ncorrect; drop the unconditional one. hif2 is already initialised to NULL.","modified":"2026-09-18T03:48:37.791118293Z","published":"2026-09-17T16:09:00.880Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90354.json"},"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/249cbaa1873550689fab136b74982cbba74c4169"},{"type":"WEB","url":"https://git.kernel.org/stable/c/29fbc5256c2d8448f084ff179d2e5092ecd1fc54"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3ae8ad277e2819a281b0e36b55633c8515c16ce7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/927fe8c0eb8c10295bc0018c8faa4d91f8fe98c6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bd2e8f535ae35beb45a7fcc17ec9bbf8dc4db5fe"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eac18fadc791928379b179e54636494b92f8cf86"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90354.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90354"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"cacdd67812c6df824704ac078f1770188a485ff9"},{"fixed":"eac18fadc791928379b179e54636494b92f8cf86"},{"fixed":"927fe8c0eb8c10295bc0018c8faa4d91f8fe98c6"},{"fixed":"bd2e8f535ae35beb45a7fcc17ec9bbf8dc4db5fe"},{"fixed":"249cbaa1873550689fab136b74982cbba74c4169"},{"fixed":"29fbc5256c2d8448f084ff179d2e5092ecd1fc54"},{"fixed":"3ae8ad277e2819a281b0e36b55633c8515c16ce7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90354.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.18.0"},{"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-2026-90354.json"}}],"schema_version":"1.9.0"}
