CVE-2026-68260
7.8 · HIGHOverview
CVE-2026-68260 is a high-severity vulnerability. It was published on August 10, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
drm/imagination: acquire vm_ctx->lock before mapping memory to GPU VM
The drm gpuvm code doesn't protect find operation against map operation,
and the driver needs to ensure a map operation shouldn't happen when a
find operation is in progress.
In some cases a find operation will be in progress when doing map/unmap
operations, and the find operation will do a NULL pointer dereference.
An example of the stack trace of such NULL dereference is shown below:
```
