CVE-2026-16280: GPU DDK - Integer overflow in _PMRLogicalOffsetToPhysicalOffset
- Severity: critical (CVSS 9.8 v3.1)
- Exploited in the wild: not listed in CISA KEV

- Public exploit or detection template: none known
- Published: 2026-07-24 · updated 2026-10-24
- Weakness: CWE-190
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.
Affected products
- Imagination Technologies Graphics DDK: before 26.1; 26.1-rtm1 — fixed in 26.1
