{"id":"AZL-108131","summary":"CVE-2026-98426 affecting package kernel 6.6.157.1-1","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":"2026-10-15T14:17:17.008731968Z","published":"2026-10-14T14:17:54Z","upstream":["CVE-2026-98426"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98426"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-108131.json"}}],"schema_version":"1.9.0"}
