n the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix NULL access in assign channel context handler Currently, when ath12k_mac_assign_vif_to_vdev() fails, the radio handle (ar) gets accessed from the link VIF handle (arvif) for debug logging, This is incorrect. In the fail scenario, radio handle is NULL. Fix the NULL access, avoid radio handle access by moving to the hardware debug logging helper function (ath12k_hw_warn). Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: ath12k: corrección del acceso nulo en el controlador de contexto de asignación de canal. Actualmente, cuando ath12k_mac_assign_vif_to_vdev() falla, se accede al controlador de radio (ar) desde el controlador VIF del enlace (arvif) para el registro de depuración. Esto es incorrecto. En el escenario de fallo, el controlador de radio es nulo. Corrija el acceso nulo y evite el acceso al controlador de radio migrando a la función auxiliar de registro de depuración de hardware (ath12k_hw_warn). Probado en: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1. Probado en: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3.
