| Severity | CVSS 7.8 - High |
|---|---|
| Actively exploited? | Not currently in CISA KEV |
| Affected | Same as the bundle - see CVE-2026-22165 |
| Fixed in | Same patched build as CVE-2026-22165 (26.1 RTM) |
| Type (CWE) | CWE-119: CWE - CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer (4.18) |
What's different about CVE-2026-22167?
Software installed and run as a non-privileged user may conduct improper GPU system calls to force GPU to write to arbitrary physical memory pages.
Under certain circumstances this exploit could be used to corrupt data pages not allocated by the GPU driver but memory pages in use by the kernel and drivers running on the platform altering their behaviour.
This attack can lead the GPU to perform write operations on restricted internal GPU buffers that can lead to a second order affect of corrupted arbitrary physical memory.
The technical impact and remediation are identical to the primary CVE in the bundle. The same vendor patch closes both.
