CVE-2026-64246: power: reset: linkstation-poweroff: fix use-after-free in the linkstation_poweroff_init()
In the Linux kernel, the following vulnerability has been resolved:
power: reset: linkstation-poweroff: fix use-after-free in the linkstationpoweroffinit()
Move ofnodeput(dn) after the ofmatchnode() call, which still needs the node pointer. The node reference is correctly released after use.

Frequently Asked Questions
Who is realistically exposed, and what access does an attacker need?
Exposure is limited to Linux kernel systems that use the linkstation-poweroff reset/power-off driver and execute its initialization path. Exploitation requires local access with low privileges; the provided CVSS vector does not indicate a network or user-interaction requirement.
What is the available remediation?
A patch is available. The fix keeps the device-tree node reference valid until after of_match_node() has finished using it, then releases the reference.
How can I determine whether a system may be affected?
The supplied information does not identify affected kernel versions or a configuration setting that determines whether the driver is enabled. Assess exposure by determining whether the running kernel includes and initializes the linkstation-poweroff driver, then compare it with the available stable fixes.
