Chacha20Poly1305 key-encryption algorithm discards the Poly1305 authentication tag, performing no authentication on decryption

Impact The experimental Chacha20Poly1305 key-encryption algorithm generates the 16-byte Poly1305 authentication tag during encryptKey but discards it: the tag is never written to the header and therefore never reaches the wire. On the receiving side, decryptKey calls...

CVE-2026-48131

The VPN service may mishandle an unexpected IKE fragment value received on the IKE port 500/UDP during the early stage of a connection attempt. This can cause the service to terminate unexpectedly, resulting in denial of service temporary disruption of VPN-related functionality...

CVE-2026-50751 - User Authentication bypass on VPN Remote Access and Mobile Access in deprecated IKEv1 key exchange

Symptoms - An attacker can bypass user authentication by exploiting a logic flow weakness in the Remote Access and Mobile Access certificate validation and establish a remote access VPN connection without a valid user password. Check Point is aware of this vulnerability being exploited in the wil...

CVE-2026-48132

The Security Gateway does not correctly validate a length value in certain IKE packets when NAT-T is used 4500/UDP. As a result, a specially crafted or malformed packet can cause the VPN processing service to terminate unexpectedly, leading to denial of service temporary interruption of VPN...

CVE-2026-49323

Weak authentication between the Wireless Control Module WCM and the Engine Control Module ECM of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker with read access to the in-vehicle network to recover the per-vehicle ECM immobilizer secret by passively...

CVE-2026-49323

The CVE concerns the Indian Motorcycle Scout Bobber + Tech 2025 model year WCM–ECM link. Weak authentication allows an adjacent-network attacker with read access to passively capture one seed/key exchange and recover the per-vehicle immobilizer secret because the WCM’s response uses a reversible,...

PT-2026-44829

Name of the Vulnerable Software and Affected Versions Indian Motorcycle Scout Bobber + Tech 2025 model year Description Weak authentication exists between the Wireless Control Module WCM and the Engine Control Module ECM. An adjacent-network attacker with read access to the in-vehicle network can...

Efficient and Quantum-Safe Internet Key Exchange Protocols for Satellite Communications

This paper studies cryptographic key exchange in satellite communications, which requires specific solutions because the satellite context presents unique challenges, particularly concerning onboard resource constraints and long transmission latency. We address these challenges by considering the...

ALPINE-CVE-2026-5260

A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure...
