What to do
AI-suggested
A fix is available that clears the IRQ affinity hint before freeing the IRQ in the error path of the ath12k driver. Users should apply the updated Linux kernel version containing this fix. No additional mitigation is required beyond applying the patch.
Description
CVE-2025-22128 is a medium severity vulnerability in the Linux kernel's ath12k Wi-Fi driver. It involves improper handling of the IRQ affinity hint in error paths when freeing IRQs. If a shared IRQ is used, the affinity hint may not be cleared before freeing, causing a warning from the IRQ core. The issue is fixed by clearing the affinity hint before calling the IRQ free function in the error path.
