Official description
NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the open-source kernel module Resource Server where an unprivileged local user could cause a use-after-free through a missing self-reference guard in the map cleanup path. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, denial of service, information disclosure, and data tampering.

The underlying weakness: Use After Free
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory belongs to the code that operates on the new pointer.
How developers prevent this class of flaw
- Choose a language that provides automatic memory management.
- When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
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).
