CVE-2026-92496

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.
