CVE-2026-74912 · Severity: info · Published 2026-10-30

Imagination Technologies' GPU driver (DDK) contains an integer truncation flaw when mapping graphics buffers in the 0GB–4GB range. The vulnerability was introduced as a side effect of fixing a prior security issue, causing mapping errors that degrade GPU functionality and may prevent legitimate applications from accessing graphics memory correctly.

## Technical details

Integer truncation occurs in the kernel mode driver when handling GPU buffer page mappings within the 0GB–4GB address range, resulting in functional errors and limited GPU driver capability. The flaw was inadvertently introduced by the fix for CVE-2026-49746. No privilege escalation or security boundary bypass is described; the impact is primarily a loss of functionality rather than a security exploit.
