CVE-2026-90361

wifi: ath11k: fix leak in ath11k_service_ready_ext_event()

Published Sep 17, 2026 CVSS n/a EPSS < 1% KEV · Not listed

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.
