n the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix crash when unbinding If there is an error during some initialization related to firmware, the function ath12k_dp_cc_cleanup is called to release resources. However this is released again when the device is unbinded (ath12k_pci), and we get: BUG: kernel NULL pointer dereference, address: 0000000000000020 at RIP: 0010:ath12k_dp_cc_cleanup.part.0+0xb6/0x500 [ath12k] Call Trace: ath12k_dp_cc_cleanup ath12k_dp_free ath12k_core_deinit ath12k_pci_remove ... The issue is always reproducible from a VM because the MSI addressing initialization is failing. In order to fix the issue, just set to NULL the released structure in ath12k_dp_cc_cleanup at the end.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: ath12k: se corrige el fallo al desvincular Si hay un error durante alguna inicialización relacionada con el firmware, se llama a la función ath12k_dp_cc_cleanup para liberar recursos. Sin embargo, esto se libera de nuevo cuando se desvincula el dispositivo (ath12k_pci), y obtenemos: ERROR: desreferencia de puntero NULL del kernel, dirección: 0000000000000020 en RIP: 0010:ath12k_dp_cc_cleanup.part.0+0xb6/0x500 [ath12k] Seguimiento de llamadas: ath12k_dp_cc_cleanup ath12k_dp_free ath12k_core_deinit ath12k_pci_remove ... El problema siempre se puede reproducir desde una máquina virtual porque la inicialización del direccionamiento MSI está fallando. Para solucionar el problema, simplemente establezca en NULL la estructura liberada en ath12k_dp_cc_cleanup al final.
