This issue affects an unknown part of the component AMD RAID Driver. The manipulation with an unknown input leads to a insufficient granularity of access control vulnerability. Using CWE to declare the problem leads to CWE-1220. The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Improper Input Validation in the AMD RAID driver could allow an attacker to point to an arbitrary memory location potentially resulting in privilege escalation and arbitrary code execution.

It is possible to read the advisory at amd.com. The identification of this vulnerability is CVE-2024-21962 since 01/03/2024. The exploitation is known to be easy. Attacking locally is a requirement. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 05/15/2026).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
