CVE-2026-41564

A flaw was found in CryptX. CryptX versions before 0.088 for Perl do not properly reseed the pseudo-random number generator PRNG state after a process forks. This vulnerability allows an attacker to recover the signing private key by observing two signatures from different child processes, as the...

CVE-2026-41564
