Technical description

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath11k: fix error path leaks in some WMI WOW calls

Fix two instances where we used to directly return the result of

ath11k_wmi_cmd_send(...). Because we did not check the return value, we

also did not free the skb in the error path.

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.
