CVE-2022-2274: RSA implementation bug in AVX512IFMA instructions
The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X8664 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X8664 architecture are affected by this issue.
