Graphics DDK: Incorrect Pointer Scaling
CVE-2026-34194 is a high-severity incorrect pointer scaling vulnerability in Graphics DDK from Imagination Technologies, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. Affected Graphics DDK versions: 24.2 RTM; 25.1 RTM through 25.3 RTM; 26.1 RTM. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.12% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Graphics DDK you run against the affected versions below, and install the vendor's latest release.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Imagination Technologies | Graphics DDK | 24.2 RTM; 25.1 RTM through 25.3 RTM; 26.1 RTM | Not stated |
Version data comes from the organisation that assigned the CVE. Confirm against the vendor advisory before deciding you are unaffected.
How the severity score breaks down
- Attack vector
- LocalThe attacker needs local access or must trick a user into running something.
- Attack complexity
- LowNo special conditions are needed; the attack works reliably.
- Privileges required
- LowA basic user account is enough.
- User interaction
- NoneNo action by a victim is required.
- Scope
- UnchangedImpact stays within the vulnerable component.
- Confidentiality
- NoneNo data is disclosed.
- Integrity
- HighData or code can be modified at will.
- Availability
- HighThe component can be taken down completely.
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H. Scored by CISA (ADP).
Official description
Software installed and run as a non-privileged user may conduct improper GPU system calls to cause mismanagement of a mapping state maintained for a sparse memory allocation. The product accidentally refers to the wrong memory due to the semantics of how math operations are implicitly scaled across buffers of different sizes.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Incorrect Pointer Scaling
In C and C++, one may often accidentally refer to the wrong memory due to the semantics of when math operations are implicitly scaled.
How developers prevent this class of flaw
- Use a platform with high-level memory abstractions.
- Always use array indexing instead of direct pointer manipulation.
- Use technologies for preventing buffer overflows.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: total).
- Record last changed materially (score, affected products, status or references).
