In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: Avoid buffer overread in ath11k_wmi_tlv_op_rx()
Currently, in ath11k_wmi_tlv_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.
Add an upfront length check before dereferencing skb->data as a
wmi_cmd_hdr. The check is placed before the trace_ath11k_wmi_event()
call to preserve the existing trace semantics (tracing the full raw
WMI event including the header), unlike the analogous ath12k fix which
could use skb_pull_data() directly.
Compile tested only.
