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)

CVSS

NVD hasn't assigned a CVSS score to this CVE (common since the April 2026 policy change).

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.21 %
Percentile among all scored CVEs: 10
Score date: 10/20/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
