{"id":"CVE-2026-98426","summary":"wifi: mwifiex: fix IRQ leak using wrong index in MSI-X error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mwifiex: fix IRQ leak using wrong index in MSI-X error path\n\nmwifiex_pcie_request_irq() registers each MSI-X vector with a per-index\ndev_id (&card-\u003emsix_ctx[i]). On a request_irq() failure the cleanup loop\n\"for (j = 0; j \u003c i; j++)\" frees msix_entries[j].vector but passes the\nfailed index's &card-\u003emsix_ctx[i] as the dev_id. free_irq() matches on\n(irq, dev_id), so it fails to find the action registered with\n&card-\u003emsix_ctx[j]: the already-requested IRQ j is not freed (leaked) and\nfree_irq() warns about freeing a non-existent IRQ. Use &card-\u003emsix_ctx[j].","modified":"2026-10-15T02:47:42.423813640Z","published":"2026-10-14T13:27:53.177Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98426.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/03d5e4776e8b71c2468c5c3c48b39202c87a8796"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0969c9688389f2e0f65b1a924b0dd6625a3bb776"},{"type":"WEB","url":"https://git.kernel.org/stable/c/11bc2cbb14f450eaa47cce9eb086f948ef8f4bcd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1a60cb2292194cc9eafae7ca8a8a72d37ae78d97"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2761b21cb896b1da8dd46cee5084c9032b2d7098"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5fd4cc87e6cc0839aac89c24ebe39ce262fe088f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a3d722190cdef18da4878b5efc27c3c386dda248"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fcac5813f324cd07dfd36b4adf624fc70f7587d6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98426.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98426"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"99074fc1e67b374b5c72406a23ac01fed806d634"},{"fixed":"11bc2cbb14f450eaa47cce9eb086f948ef8f4bcd"},{"fixed":"1a60cb2292194cc9eafae7ca8a8a72d37ae78d97"},{"fixed":"fcac5813f324cd07dfd36b4adf624fc70f7587d6"},{"fixed":"2761b21cb896b1da8dd46cee5084c9032b2d7098"},{"fixed":"5fd4cc87e6cc0839aac89c24ebe39ce262fe088f"},{"fixed":"0969c9688389f2e0f65b1a924b0dd6625a3bb776"},{"fixed":"03d5e4776e8b71c2468c5c3c48b39202c87a8796"},{"fixed":"a3d722190cdef18da4878b5efc27c3c386dda248"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98426.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.6.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.54"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98426.json"}}],"schema_version":"1.9.0"}
