CVE-2026-16280

GPU DDK - Integer overflow in _PMRLogicalOffsetToPhysicalOffset

Published Jul 24, 2026 CVSS 3.1 · 9.8 Critical EPSS < 1% KEV · Not listed
Description
An integer overflow when calculating physical offsets for sparse PMRs may result in 32-bit truncation of address computations for PMRs larger than 4 GB. This can lead to incorrect GPU MMU mappings and may allow a non-privileged user to trigger access to unintended physical memory, resulting in memory corruption or information disclosure.
