Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: Clear affinity hint before calling ath11k_pcic_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 ath11k_pci_alloc_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 free_irq+0x278/0x29c Call trace: free_irq+0x278/0x29c ath11k_pcic_free_irq+0x70/0x10c [ath11k] ath11k_pci_probe+0x800/0x820 [ath11k_pci] local_pci_probe+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 ath11k_pcic_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. Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-05266-QCAHSTSWPLZ_V2_TO_X86-1

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: ath11k: Borrar la indicaci\u00f3n de afinidad antes de llamar a ath11k_pcic_free_irq() en la ruta de error. Si el controlador utiliza una IRQ compartida debido a una limitaci\u00f3n de la plataforma, la indicaci\u00f3n de afinidad de IRQ se establece justo despu\u00e9s de la asignaci\u00f3n de vectores IRQ en ath11k_pci_alloc_msi(). Esto no causa ning\u00fan problema a menos que una de las funciones que solicita la IRQ falle e intente liberarla. Esto da como resultado la siguiente advertencia: ADVERTENCIA: CPU: 7 PID: 349 en kernel/irq/manage.c:1929 free_irq+0x278/0x29c Rastreo de llamadas: free_irq+0x278/0x29c ath11k_pcic_free_irq+0x70/0x10c [ath11k] ath11k_pci_probe+0x800/0x820 [ath11k_pci] local_pci_probe+0x40/0xbc La advertencia se debe a que no se borra la sugerencia de afinidad antes de liberar las IRQ. Por lo tanto, para solucionar este problema, borre la sugerencia de afinidad de IRQ antes de llamar a ath11k_pcic_free_irq() en la ruta de error. La afinidad se borrar\u00e1 una vez m\u00e1s m\u00e1s adelante en la ruta de error debido a la organizaci\u00f3n del c\u00f3digo, pero eso no hace da\u00f1o.
