CVE-2026-92496

/// Technical description

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.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
