CVE-2026-64246 Details
Description
In the Linux kernel, the following vulnerability has been resolved: power: reset: linkstation-poweroff: fix use-after-free in the linkstation_poweroff_init() Move of_node_put(dn) after the of_match_node() call, which still needs the node pointer. The node reference is correctly released after use.
A use-after-free vulnerability has been identified in the Linux kernel's power reset Linkstation power-off driver. This issue arises in the 'linkstation_poweroff_init()' function, where the reference to a device node is released before it is no longer needed, potentially leading to memory management errors. The vulnerability affects the stable version of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the latest kernel version can be found on the official Linux kernel website.
