In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: Clear affinity hint before calling ath11kpcicfree_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 ath11kpcialloc_msi(). This does no harm unless one of the functions requesting the IRQ fails and attempt to free the IRQ. This results in the below warning:
WARNING: CPU: 7 PID: 349 at kernel/irq/manage.c:1929 freeirq+0x278/0x29c Call trace: freeirq+0x278/0x29c ath11kpcicfreeirq+0x70/0x10c [ath11k] ath11kpciprobe+0x800/0x820 [ath11kpci] localpciprobe+0x40/0xbc
The warning is due to not clearing the affinity hint before freeing the IRQs.
So to fix this issue, clear the IRQ affinity hint before calling ath11kpcicfree_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.
