CVE-2022-49971

Service interruption via unreleased GPU metrics allocation

Published Jun 18, 2025 · Updated May 11, 2026

Memory leak in Linux kernel 5.19 through 5.19.6 allows local users to exhaust memory through AMD GPU power-management teardown. smu_v13_0_4_init_smc_tables() allocates gpu_metrics_table, but smu_v13_0_4_fini_smc_tables() omits the corresponding free. The flaw requires local low-privileged access and an affected AMD GPU path; its documented consequence is unreleased memory that can interrupt service.
