CVE-2026-64155 Details
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.
A vulnerability in the Linux kernel's ath11k wireless driver has been addressed, which involved improper error handling in certain Wake on Wireless (WoW) commands. The issue arose because the return value of a command sending function was not checked, leading to a failure to free a buffer in case of an error. This vulnerability affects the Linux kernel stable tree.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
