CVE-2026-63810

In the Linux kernel, the following vulnerability has been resolved: block: Avoid mounting the bdev pseudo-filesystem in userspace The bdev pseudo-filesystem is an internal kernel filesystem with which userspace should not interfere. Unregister it so that userspace cannot even attempt to mount it...

CVE-2026-63810

In CVE-2026-63810, the Linux kernel fixed a vulnerability in the block subsystem by unregistering the bdev pseudo-filesystem to prevent userspace from mounting it. The issue arose because move_mount() could use inode_operations pointers that were always zero for this filesystem, enabling a NULL p...

CVE-2026-38968: Predictable from Observable State

ntopng through 6.6 is vulnerable to Predictable Session Identifier which can lead to Session Hijacking. HTTP session identifiers in src/HTTPserver.cpp use weak time-seeded pseudo-randomness during session creation. As a result, fresh authenticated logins can receive deterministic or colliding...

CVE-2026-57082

Net::BitTorrent versions before 2.1.0 for Perl generate the MSE Diffie-Hellman private key with a non-cryptographic PRNG. The MSE Message Stream Encryption handshake derives its 160-bit Diffie-Hellman private key from Perl's rand, a non-cryptographic drand48-class generator seeded once per proces...

CVE-2026-57082

Net::BitTorrent for Perl, in versions before 2.1.0 (and specifically through 2.0.1 in some records), is vulnerable to a cryptographic failure because it uses a non-cryptographic PRNG (Perl's rand() ) to generate the MSE Diffie-Hellman private key in KeyExchange.pm. Because this PRNG is seeded onc...

PYSEC-2026-407 Marimo: Pre-Auth Remote Code Execution via Terminal WebSocket Authentication Bypass

Summary Marimo 19.6k stars has a Pre-Auth RCE vulnerability. The terminal WebSocket endpoint /terminal/ws lacks authentication validation, allowing an unauthenticated attacker to obtain a full PTY shell and execute arbitrary system commands. Unlike other WebSocket endpoints e.g., /ws that correct...

CVE-2026-11702

Bytes::Random::Secure::Tiny versions through 1.011 for Perl share internal state across forked processes. When an object is initialised before forking, then the internal state for the PRNG is shared across processes and identical random streams will be produced. Secrets generated in multiprocess...
