CRITICAL

Imagination Technologies Graphics DDK - GPU DDK - Integer Overflow in _PMRLogicalOffsetToPhysicalOffset

Title source: rule

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.
