librenswan: IKEv1 Denial of Service via RSA-SHA1 (PKCS#1 Version 1.5 Encrypted) authentication payload

A flaw was found in Libreswan's implementation of IKEv1 authentication via raw RSA signatures. When processing an IKEv1 packet using PKCS 1 v1.5 RSA encryption, the RSAauthenticatehashsignaturerawrsa function fails to properly validate the length of the authentication hash. A remote,...

CVE-2026-50720: Improper Verification of Cryptographic Signature

The Ingenic T31 SoC boot ROM flash-boot verification path compares only a single 32-bit word of the RSA signature output against a single 32-bit word of the SHA-256 payload digest, rather than compare the full data. This allows an attacker with physical write access to boot media to forge modifie...
