1) Missing Release of Resource after Effective Lifetime (CVE-ID: CVE-2026-98519)

CWE-ID: CWE-772 - Missing Release of Resource after Effective Lifetime

CVSSv4: 1.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a local privileged user to keep the GPU awake and increase power consumption by preventing runtime suspension.

The vulnerability exists due to a missing release of a runtime power management reference in amdgpu_debugfs_test_ib_show() when acquisition of the reset domain semaphore's write lock is interrupted. A local privileged user can invoke the debugfs test operation and interrupt its lock acquisition to leave the runtime power management reference held, preventing the GPU from entering runtime suspension.
