Graphics DDK: Use of Out-of-range Pointer Offset
CVE-2026-74912 is a critical-severity use of out-of-range pointer offset vulnerability in Graphics DDK from Imagination Technologies, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Graphics DDK versions: 1.18 RTM2; 23.2 RTM2; 24.2 RTM2, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.29% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of Graphics DDK you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
On GPU systems with the security vulnerability fix for CVE-2026-49746 applied, the mapping range of graphics buffers is limited which causes errors when the mapping outside of that range. Integer truncation caused when mapping GPU buffer pages in the buffer’s range 0GB - 4GB, produces error and limits the functionality of the kernel mode driver.

The underlying weakness: Use of Out-of-range Pointer Offset
The product performs pointer arithmetic on a valid pointer, but it uses an offset that can point outside of the intended range of valid memory locations for the resulting pointer.
