EUVD-2026-62711

Improper cryptographic signature verification in jstfunctions.c in RDK-B WebUI rdkb-2025q4-kirkstone.04.10.26 allows a remote attacker to bypass authentication and obtain administrative access via a forged JWT containing an invalid RSA signature...

EUVD-2026-62480

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

Ingenic T31 SoC boot ROM compares only one 32-bit word of RSA signature output against SHA-256 digest instead of full data, enabling SPL image forgery with ~2/3 success probability by attackers with physical boot-media access. Validated on Wyze Video Doorbell v2 (T31X). No patch or workaround det...

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...

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,...

EUVD-2026-41440

Libreswan, via the function RSAauthenticatehashsignaturepkcs115rsa, did not correctly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload was encoded using RSASSA-PKCS1-v15 RFC 8017. A remote attacker can use a variation on the Bleichenbacher attack to forge the AUTH payload...

CVE-2026-50721

Libreswan, via the function RSAauthenticatehashsignaturerawrsa, did not correctly verify the length of the authentication hash when the SIG payload of an IKEv1 packet was encoded using PKCS 1 RSA Encryption as per RFC 2313. A remote attacker can use a variation on the Bleichenbacher attack to for...

CVE-2026-50721

CVE-2026-50721 concerns Libreswan where the function RSA_authenticate_hash_signature_raw_rsa() does not properly verify the authentication hash length when the SIG payload of an IKEv1 packet is encoded using PKCS#1 RSA Encryption per RFC 2313. This enables a remote attacker to leverage a Bleichen...

CVE-2026-50722

Libreswan is affected by CVE-2026-50722 through RSA_authenticate_hash_signature_pkcs1_1_5_rsa, which fails to properly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload uses RSASSA-PKCS1-v1_5 (RFC 8017). This enables a remote attacker to perform a Bleichenbacher-like variati...

CVE-2026-33996 LibJWT has NULL/bounds validation in JWK octet and RSA PSS parsing

LibJWT is a C JSON Web Token Library. Starting in version 3.0.0 and prior to version 3.3.0, the JWK parsing for RSA-PSS did not protect against a NULL value when expecting to parse JSON string values. A specially crafted JWK file could exploit this behavior by using integers in places where the...

CVE-2026-33894

A flaw was found in Forge also called node-forge, a JavaScript implementation of Transport Layer Security. A remote attacker could exploit weaknesses in the RSASSA PKCS1 v1.5 signature verification process. By crafting malicious signatures that include extra data within the ASN structure and do n...

CVE-2026-33894 Forge has signature forgery in RSA-PKCS due to ASN.1 extra field

Forge also called node-forge is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, RSASSA PKCS1 v1.5 signature verification accepts forged signatures for low public exponent keys e=3. Attackers can forge signatures by stuffing “garbage” bytes within the ASN...
