CVE-2026-41564

CryptX versions before 0.088 for Perl do not reseed the Crypt::PK PRNG state after forking. The Crypt::PK::RSA, Crypt::PK::DSA, Crypt::PK::DH, Crypt::PK::ECC, Crypt::PK::Ed25519 and Crypt::PK::X25519 modules seed a per-object PRNG state in their constructors and reuse it without fork detection. A...

CVE-2026-23380

CVE-2026-23380 (Linux kernel) describes a local vulnerability in tracing buffers memory management. When a process forks, the child’s VMAs copy the parent’s without incrementing user_mapped, so exiting both processes may cause tracing_buffers_mmap_close() to run twice; on the second call user_map...
