CVE-2024-1543 (GCVE-0-2024-1543)

Vulnerability from cvelistv5 – Published: 2024-08-29 22:43 – Updated: 2024-08-30 14:19

Summary

The side-channel protected T-Table implementation in wolfSSL up to version 5.6.5 protects against a side-channel attacker with cache-line resolution. In a controlled environment such as Intel SGX, an attacker can gain a per instruction sub-cache-line resolution allowing them to break the cache-line-level protection. For details on the attack refer to: https://doi.org/10.46586/tches.v2024.i1.457-500
