AZL-98441 CVE-2026-14957 affecting package libreswan for versions less than 4.15-3

In FIPS mode, Libreswan's adddecodedcert function calls CERTExtractPublicKey and asserts that the result is not NULL. However, CERTExtractPublicKey returns NULL when public key extraction fails, for example if the RSA exponent is set to 0. A remote attacker can send a malformed X.509 certificate ...

CVE-2026-14957

CVE-2026-14957 is a denial-of-service vulnerability in Libreswan (an IPsec/IKE implementation for Linux). In FIPS mode , the add_decoded_cert() function calls CERT_ExtractPublicKey() and asserts the result is non-NULL. When public key extraction fails (e.g., RSA exponent set to 0), the assertion ...

CVE-2026-80606

A flaw was found in the Linux kernel's drm/xe/userptr component. When a specific test configuration is enabled, the system attempts to perform a write operation while holding a read-only lock. This incorrect lock handling leads to an assertion failure, which can cause system instability or a deni...

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,...

libreswan: badly formatted X.509 certificate can cause an assertion failure that crashes the daemon process

A flaw was found in Libreswan. An unauthenticated remote attacker can send a specially crafted X.509 certificate payload during an IKEv1 or IKEv2 exchange. This flaw occurs when Libreswan is operating in FIPS Federal Information Processing Standards mode and processing a certificate with an inval...

librenswan: IKEv2 Denial of Service via malformed fragmentation

A flaw was found in Libreswan's IKEv2 fragment reassembly mechanism. When a VPN gateway processes incoming split network packets fragments containing unexpected data, an off-by-one boundary validation error triggers an internal program safety check assertion failure. A remote, unauthenticated...
