CVE-2025-46709Network attack vector

Kernel crash via invalid pointer use

Published Aug 8, 2025 · Updated Aug 11, 2025

Use-after-free in Imagination Technologies Graphics DDK allows remote attackers to trigger kernel exceptions or consume kernel memory. The kernel module's security-fix path leaks allocations or races while handling a pointer, leading it to read freed heap memory or dereference an uninitialized or NULL pointer. The public record does not identify the affected function or explain how remote input reaches this kernel-module path.
