Intel(R) VROC software: NULL Pointer Dereference
CVE-2022-29508 is a high-severity NULL pointer dereference vulnerability in Intel(R) VROC software, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. Affected Intel(R) VROC software versions: before version 7.7.6.1003. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.17% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Virtual Raid On Cpu to 7.7.6.1003 or a later version.
- Read the advisory on intel.com for workarounds and exact fixed builds.

Official description
Null pointer dereference in the Intel(R) VROC software before version 7.7.6.1003 may allow an authenticated user to potentially enable escalation of privilege via local access.

The underlying weakness: NULL Pointer Dereference
The product dereferences a pointer that it expects to be valid but is NULL.
How developers prevent this class of flaw
- For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished.
- Select a programming language that is not susceptible to these issues.
- Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
