CVE-2026-34875

A flaw was found in Mbed TLS and TF-PSA-Crypto. This vulnerability, a buffer overflow, occurs during the export of public keys for FFDH Finite Field Diffie-Hellman keys. A remote attacker could exploit this to potentially execute arbitrary code, gaining full control over the affected system, or...

CVE-2026-34872

A flaw was found in Mbed TLS and TF-PSA-Crypto. This vulnerability, stemming from improper input validation in the finite-field Diffie-Hellman FFDH key exchange, allows a remote attacker to force the shared secret into a small, predictable set of values. This lack of contributory behavior can...

CVE-2026-34877

An issue was discovered in Mbed TLS versions from 2.19.0 up to 3.6.5, Mbed TLS 4.0.0. Insufficient protection of serialized SSL context or session structures allows an attacker who can modify the serialized structures to induce memory corruption, leading to arbitrary code execution. This is cause...

Mbed TLS 安全漏洞

Mbed TLS is an open-source, portable, easy-to-use, readable, and flexible SSL library developed by Mbed TLS. Versions of Mbed TLS prior to 3.6.6 contained security vulnerabilities. These vulnerabilities stemmed from a lack of validation for the taglen parameter in the mbedtlsccmfinish function,...

This is cause...

CVE-2026-34876

An issue was discovered in Mbed TLS 3.x before 3.6.6. An out-of-bounds read vulnerability in mbedtlsccmfinish in library/ccm.c allows attackers to obtain adjacent CCM context data via invocation of the multipart CCM API with an oversized taglen parameter. This is caused by missing validation of t...
