librenswan: IKEv2 Denial of Service via RSA-SHA1 (PKCS#1 RSASSA-PKCS1-v1_5) authentication payload

A flaw was found in Libreswan's implementation of IKEv2 authentication when processing signatures utilizing the RSASSA-PKCS1-v15 scheme. The RSAauthenticatehashsignaturepkcs115rsa function does not correctly validate the DER encoding of the ASN.1 digest. A remote, unauthenticated attacker could...

EUVD-2026-68462

Phison PS3111-S11 controller firmware verifies RSA signatures using a public modulus embedded within the firmware image itself rather than anchored in immutable storage. Attackers can generate arbitrary RSA key pairs, sign modified firmware with the private key, embed the matching modulus in the...

CVE-2026-50720

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...

CVE-2026-50720

CVE-2026-50720 affects the Ingenic T31 SoC boot ROM flash-boot verification path. The root cause is a partial signature comparison : only a single 32-bit word of the RSA signature output is checked against a single 32-bit word of the SHA-256 payload digest, rather than the full digest. An attacke...
