Network-access privilege escalation
Published May 10, 2023 · Updated Jan 27, 2025
Improper buffer restrictions in Intel QAT Engine for OpenSSL before 0.6.16 allow remote attackers to gain elevated privileges via network access. Intel does not identify the affected buffer, the input that reaches it, or the operation that fails to enforce its bounds. The published assessment requires user interaction and high attack complexity; successful exploitation grants elevated privileges, but Intel does not state the resulting privilege level.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
