In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Avoid buffer overread in ath12k_wmi_op_rx()
Currently, in ath12k_wmi_op_rx(), the firmware buffer is read without
first verifying that the buffer has enough data to hold a header. This
could result in a buffer overread.
Update the logic to verify the buffer contains at least enough data to
hold a wmi_cmd_hdr before reading from the buffer.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c7-00108-QCAHMTSWPL_V1.0_V2.0_SILICONZ_UPSTREAM-3
