CVE-2026-81015

Kernel crash via stale LPS0 registration

Published Sep 11, 2026 · Updated Sep 11, 2026

Resource cleanup error in the AMD PMC driver in Linux 6.14 allows attackers to crash the kernel via unspecified vectors. The amd_pmc_probe() failure path returns after amd_stb_s2d_init() fails without removing its debugfs directory or unregistering amd_pmc_s2idle_dev_ops, leaving callbacks backed by released resources. The condition requires an AMD PMC system where STB initialization fails; module reload or a later s2idle transition then reaches the stale state.
