CVE-2025-22866 Timing sidechannel for P-256 on ppc64le in crypto/internal/nistec

Due to the usage of a variable time instruction in the assembly implementation of an internal function, a small number of bits of secret scalars are leaked on the ppc64le architecture. Due to the way this function is used, we do not believe this leakage is enough to allow recovery of the private...

GHSA-C38W-74PG-36HR Marvin Attack: potential key recovery through timing sidechannels

Impact Due to a non-constant-time implementation, information about the private key is leaked through timing information which is observable over the network. An attacker may be able to use that information to recover the key. Patches No patch is yet available, however work is underway to migrate...

GHSA-4GRX-2X9W-596C Marvin Attack: potential key recovery through timing sidechannels

The Marvin Attack is a timing sidechannel vulnerability which allows performing RSA decryption and signing operations as an attacker with the ability to observe only the time of the decryption operation performed withthe private key. A recent survey of RSA implementations found that the Rust rsa...
