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.
