Descriptions

In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: fix possible out-of-bound write in ath12k_wmi_ext_hal_reg_caps() reg_cap.phy_id is extracted from WMI event and could be an unexpected value
in case some errors happen. As a result out-of-bound write may occur to
soc->hal_reg_cap. Fix it by validating reg_cap.phy_id before using it. This is found during code review. Compile tested only.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: wifi: ath12k: corrige una posible escritura fuera de los límites en ath12k_wmi_ext_hal_reg_caps() reg_cap.phy_id se extrae del evento WMI y podría ser un valor inesperado en caso de que ocurran algunos errores. Como resultado, puede ocurrir una escritura fuera de los límites en soc->hal_reg_cap. Solucionarlo validando reg_cap.phy_id antes de usarlo. Esto se encuentra durante la revisión del código. Compilación probada únicamente.
