Privilege escalation via unchecked RSA decryption faults
Published Aug 29, 2024 · Updated Jan 27, 2026
Fault injection in wolfSSL wolfCrypt 5.6.6 and earlier allows local users to disclose RSA key data and escalate privileges through Rowhammer. RsaPrivateDecrypt returns decrypted output without revalidating the RSA private value after the operation, so a bit flip in the RsaKey structure can affect the result. Exploitation requires co-residency with a victim process performing RSA private decryption and the ability to induce a Rowhammer memory fault.

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.
