CVE-2026-15465: GPU DDK - Write UAF in OSDebugSignalPID due to incorrect management of PID resources
Software installed and run as a non-privileged user may conduct improper GPU system calls through the DDK kernel module interface. Under unsupported use of the interface, a use-after-free condition may occur that can lead to kernel memory corruption, platform instability, or system reboot.
The weakness occurs when software references memory after it has been released. Accessing memory after free may result in corruption of valid data structures, unexpected program behaviour, process crashes, or execution of unintended operations.

Frequently Asked Questions
Who can trigger this issue?
Software installed and run as a non-privileged user can trigger the condition through GPU system calls made via the DDK kernel module interface.
What does exploitation require?
Exploitation requires unsupported use of the DDK kernel module interface and improper GPU system calls. The supplied information does not state that remote access or elevated privileges are required.
What impact could this have?
The use-after-free condition can cause kernel memory corruption, platform instability, or a system reboot. It may also result in corrupted data structures, process crashes, or unintended operations.
