CVE-2024-35809

Kernel crash via runtime-idle driver-removal race

Published May 17, 2024 · Updated May 11, 2026

Race condition in affected Linux kernel branches allows local users to crash the kernel during PCI driver removal through runtime PM callbacks. In pci_device_remove(), pm_runtime_get_sync() can return while rtsx_pci_runtime_idle() is still executing, so driver teardown races the active callback and causes an unhandled page fault. Exploitation requires local low-privileged access and the callback to be running during driver removal; the bounded consequence is a kernel crash.
