For X86 64 CPUs supporting the AVX512IFMA instructions, an important bug in the RSA implementation was introduced with OpenSSL 3.0.4. This problem causes RSA to be implemented incorrectly on these machines with 2048-bit private keys, and memory corruption will occur while the computation is done.

An attacker could cause remote code execution on the computer performing the calculation because of memory corruption. This problem affects SSL/TLS servers or other servers using 2048-bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture. 2ff7e9595c
