CVE-2026-16280

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...

PT-2026-64421

Name of the Vulnerable Software and Affected Versions GPU DDK affected versions not specified Description An integer overflow occurs during the calculation of physical offsets for sparse PMRs Partial Memory Regions within the PMRLogicalOffsetToPhysicalOffset function. For PMRs larger than 4 GB,...

CVE-2026-41158 GPU DDK - Backed sparse PMRs are not handled by deferred free mechanism after shrink

Software installed and run as a non-privileged user may conduct GPU system calls to write to arbitrary freed physical pages. Physical memory allocated and freed, without the deferred free mechanism can lead to those resources being used for read/write by the GPU after the kernel module has freed...
