CVE-2025-22128: wifi: ath12k: Clear affinity hint before calling ath12k_pci_free_irq() in error path

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.18% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 35b33ba76765ce9e72949d957f3cf1feafd2955c, a69a594794fcad96d4cfce12aab6c5014a12b4c8, b43b1e2c52db77c872bd60d30cdcc72c47df70c7.

Low priority for now. Upgrade to Linux Linux 35b33ba76765ce9e72949d957f3cf1feafd2955c, a69a594794fcad96d4cfce12aab6c5014a12b4c8, b43b1e2c52db77c872bd60d30cdcc72c47df70c7 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Clear affinity hint before calling ath12k_pci_free_irq() in error path If a shared IRQ is used by the driver due to platform limitation, then the IRQ affinity hint is set right after the allocation of IRQ vectors in ath12k_pci_msi_alloc(). This does no harm unless one of the functions requesting the IRQ fails and attempt to free the IRQ. This may end up with a warning from the IRQ core that is expecting the affinity hint to be cleared before freeing the IRQ: kernel/irq/manage.c: /* make sure affinity_hint is cleaned up */ if (WARN_ON_ONCE(desc->affinity_hint)) desc->affinity_hint = NULL; So to fix this issue, clear the IRQ affinity hint before calling ath12k_pci_free_irq() in the error path. The affinity will be cleared once again further down the error path due to code organization, but that does no harm.
