CVE-2022-0330

Privilege escalation via missing GPU TLB flush

Published Mar 25, 2022 · Updated Aug 2, 2024

Random memory access in the Linux kernel i915 driver 5.17-rc2 allows local users to disclose or corrupt memory by submitting GPU code. The driver releases GPU-buffer backing pages without first flushing stale TLB entries, so undeclared GPU accesses can continue after those pages are reassigned. Access requires a Gen8 or newer Intel GPU; without an active IOMMU, consequences include data disclosure, memory corruption, a system crash, or privilege escalation.
