CVE-2026-98519

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Fix runtime PM leak in amdgpu debugfs test ib show()

amdgpu debugfs test ib show() resumes the device with pm runtime get sync() before taking the reset domain semaphore with down write killable(). If the write lock acquisition is interrupted, the function returns without calling pm runtime put autosuspend(), leaking the runtime PM reference acquired for the device and keeping the GPU awake.

Drop the runtime PM reference on the interrupted down write killable() error path before returning.

(cherry picked from commit ec30a576c2d4c0364549e6c04218f50704ef56c8)
