{"id":"CVE-2025-22128","summary":"wifi: ath12k: Clear affinity hint before calling ath12k_pci_free_irq() in error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath12k: Clear affinity hint before calling ath12k_pci_free_irq() in error path\n\nIf a shared IRQ is used by the driver due to platform limitation, then the\nIRQ affinity hint is set right after the allocation of IRQ vectors in\nath12k_pci_msi_alloc(). This does no harm unless one of the functions\nrequesting the IRQ fails and attempt to free the IRQ.\n\nThis may end up with a warning from the IRQ core that is expecting the\naffinity hint to be cleared before freeing the IRQ:\n\nkernel/irq/manage.c:\n\n\t/* make sure affinity_hint is cleaned up */\n\tif (WARN_ON_ONCE(desc-\u003eaffinity_hint))\n\t\tdesc-\u003eaffinity_hint = NULL;\n\nSo to fix this issue, clear the IRQ affinity hint before calling\nath12k_pci_free_irq() in the error path. The affinity will be cleared once\nagain further down the error path due to code organization, but that does\nno harm.","modified":"2026-04-02T12:45:22.167802Z","published":"2025-04-16T14:13:10.692Z","related":["SUSE-SU-2025:01614-1","SUSE-SU-2025:01707-1","SUSE-SU-2025:01919-1","SUSE-SU-2025:01951-1","SUSE-SU-2025:01964-1","SUSE-SU-2025:01967-1","SUSE-SU-2025:01972-1","SUSE-SU-2025:20343-1","SUSE-SU-2025:20344-1","SUSE-SU-2025:20354-1","SUSE-SU-2025:20355-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22128.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/35b33ba76765ce9e72949d957f3cf1feafd2955c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a69a594794fcad96d4cfce12aab6c5014a12b4c8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b43b1e2c52db77c872bd60d30cdcc72c47df70c7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22128.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-22128"},{"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":"a3012f206d07fa62b5c2e384cbc3a81a4dbba3c9"},{"fixed":"a69a594794fcad96d4cfce12aab6c5014a12b4c8"},{"fixed":"35b33ba76765ce9e72949d957f3cf1feafd2955c"},{"fixed":"b43b1e2c52db77c872bd60d30cdcc72c47df70c7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-22128.json"}}],"schema_version":"1.7.5"}
