CVE-2026-65584
GPU DDK - Stack Buffer Overflow via undersized UFO address array in DumpStalledContextInfo
What happened?
Software installed and run as a non-privileged user may conduct improper GPU system calls causing a stack overflow in the kernel. The overflow occurs when processing resolved Linux/Android fence synchronization checkpoints, while user checkpoints are excluded from the stack array. Successful exploitation can cause kernel memory corruption and typically results in a denial-of-service condition through a kernel crash.
The code vulnerability is a buffer write beyond the allocated array on the stack caused by copying excessive data from an internal buffer.
Affected software and versions
| Software | Version information | Fixed version |
|---|---|---|
| Graphics DDKImagination Technologies | affected: 1.18 RTM2; affected: 23.2 RTM2; affected: 24.2 RTM2; affected: 25.1 RTM2 to ≤ 25.3 RTM; affected: 26.1 RTM2; unaffected: 26.2 RTM | See vendor advisory |
Version information comes from the source record and can include unaffected products and exceptions. Distribution packages may contain backported fixes: an older upstream version alone does not prove a server is affected.
Is it being exploited?
This CVE was not listed in the CISA catalogue at our last retrieval. This does not establish that exploitation is absent.
How to respond
- Confirm the product, installed package version, and any configuration requirements in the vendor advisory.
- Follow the vendor’s remediation or workaround guidance in the references below. Structured fixed-version data is unavailable here; the publisher’s description may include a fix or workaround.
- Restart affected services if required, then verify the running version. Known exploitation may warrant investigation as well as patching.
