Details

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Clear affinity hint before calling ath12kpcifreeirq() 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 ath12kpcimsialloc(). 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 affinityhint is cleaned up */ if (WARNONONCE(desc->affinityhint)) desc->affinityhint = NULL; So to fix this issue, clear the IRQ affinity hint before calling ath12kpcifreeirq() 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.
