{"id":"CVE-2026-90352","summary":"wifi: mt76: mt7915: release hif2 reference on probe IRQ failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7915: release hif2 reference on probe IRQ failure\n\nThe hif2 reference obtained by mt7915_pci_init_hif2() is only released on\nerror paths that key off dev-\u003ehif2, which is not assigned until after the\nIRQ setup. If pci_alloc_irq_vectors() or the primary devm_request_irq()\nfails, the reference leaks. Drop it explicitly on those paths via\nmt7915_put_hif2().","modified":"2026-09-19T03:47:26.025014066Z","published":"2026-09-17T16:08:59.557Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90352.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2a434d2637b9c9be9bcc8a84dc46880cc1446643"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5c30a6350a300fbb800831f1b4373b2f59e03410"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8370aebd26a9dfa2e0de665e3ab504c0e97ee730"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8a2e38019846da29a112fac4dd96fe5bfa298faf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ed5cc46a3c8f4fe7f549c661914d8d835169acc0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fb9c7b4c238b4e5469a11a1fb8cf332f6193b995"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90352.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90352"},{"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":"f68d67623dec9445960b52a0e9e8e60297596b4b"},{"fixed":"8a2e38019846da29a112fac4dd96fe5bfa298faf"},{"fixed":"2a434d2637b9c9be9bcc8a84dc46880cc1446643"},{"fixed":"5c30a6350a300fbb800831f1b4373b2f59e03410"},{"fixed":"ed5cc46a3c8f4fe7f549c661914d8d835169acc0"},{"fixed":"fb9c7b4c238b4e5469a11a1fb8cf332f6193b995"},{"fixed":"8370aebd26a9dfa2e0de665e3ab504c0e97ee730"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90352.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.19.0"},{"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-2026-90352.json"}}],"schema_version":"1.9.0"}
