CVE-2026-25834

A flaw was found in Mbed TLS. A remote attacker could exploit this vulnerability by performing an algorithm downgrade attack. This could lead to a reduction in the security strength of cryptographic operations, potentially allowing for information disclosure or denial of service. Mitigation...

CVE-2025-66442

A flaw was found in Mbed TLS and TF-PSA-Crypto. This vulnerability is a compiler-induced timing side channel that occurs when the LLVM compiler's select-optimize feature is enabled. A remote attacker could potentially exploit this timing difference during RSA and CBC/ECB decryption operations to...

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...
