Summary
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.
