CVE-2023-53152

Local GPU disruption via unreleased PSP buffers

Published Sep 15, 2025 · Updated Sep 15, 2025

Resource leakage in the Linux kernel allows local users to disrupt AMDGPU teardown by removing the driver on affected systems. The psp_hw_fini path can be skipped after XGMI recovery, so PSP buffer objects remain allocated until amddrm_buddy_fini detects them during teardown. The documented trigger requires an XGMI-capable SMU 13.0.2 GPU and driver removal; the public record reports a call-trace warning rather than a host crash.
