openssl: OpenSSL: Private key recovery via timing side-channel in generic elliptic curve operations

A flaw was found in OpenSSL. A timing side-channel vulnerability in generic elliptic curve scalar multiplication allows an attacker to recover private cryptographic keys. When performing signature operations, such as the Elliptic Curve Digital Signature Algorithm ECDSA or SM2, using curves withou...

openssl: OpenSSL: Private key recovery via SM2 timing side-channel

A flaw was found in OpenSSL. During SM2 signature generation, variable-time arithmetic operations are performed on secret values, creating an observable timing side-channel. An attacker capable of measuring signature generation times can collect timing data across multiple signing operations, whi...

openssl: openssl: information disclosure via non-constant-time SM2 scalar multiplication on ARM64 and RISC-V

A flaw was found in OpenSSL. The optimized scalar point multiplication used for SM2 cryptographic operations on ARM64 and RISC-V architectures does not execute in constant time. An attacker capable of measuring execution times or observing processor cache-access patterns can exploit this side...
