CVE-2024-36018

Kernel crash via UVMM remap range miscalculation

Published May 30, 2024 · Updated Aug 5, 2026

Out-of-bounds writes in the Linux kernel's nouveau UVMM allow local users to crash affected systems through a crafted GPU remap. The remap path calculates the previous mapping's unmap address and range directly instead of deriving start and end boundaries, so the oversized unmap corrupts GPU page tables. A low-privileged local user must reach nouveau's VM_BIND sparse-resource remap path on a system using the affected driver; the documented result is a kernel oops and service interruption.
