CVE-2026-90361

/// Technical description

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

wifi: ath11k: fix leak in ath11k_service_ready_ext_event()

Currently, during ath11k_service_ready_ext_event() processing,

svc_rdy_ext.mac_phy_caps can be allocated during TLV parsing. This is a

temporary allocation that is freed on the success path, but not on the

error path. If parsing succeeds far enough to allocate mac_phy_caps and

then fails on a later TLV, the allocation leaks. So free the allocation

on the error path.

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.
