CVE-2026-34875: Buffer Copy without Checking Size of Input

An issue was discovered in Mbed TLS through 3.6.5 and TF-PSA-Crypto 1.0.0. A buffer overflow can occur in public key export for FFDH keys...

CVE-2026-34871: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

An issue was discovered in Mbed TLS before 3.6.6 and 4.x before 4.1.0 and TF-PSA-Crypto before 1.1.0. There is a Predictable Seed in a Pseudo-Random Number Generator PRNG...

CVE-2026-34872: Improper Verification of Cryptographic Signature

An issue was discovered in Mbed TLS 3.5.x and 3.6.x through 3.6.5 and TF-PSA-Crypto 1.0. There is a lack of contributory behavior in FFDH due to improper input validation. Using finite-field Diffie-Hellman, the other party can force the shared secret into a small set of values lack of contributor...

CVE-2025-66442

In Mbed TLS through 4.0.0, there is a compiler-induced timing side channel in RSA and CBC/ECB decryption that only occurs with LLVM's select-optimize feature. TF-PSA-Crypto through 1.0.0 is also affected...

CVE-2026-25835

Mbed TLS versions prior to 3.6.6 and TF-PSA-Crypto versions prior to 1.1.0 are vulnerable to a security flaw involving the misuse of seeds in a Pseudo-Random Number Generator (PRNG) . This vulnerability can impact the cryptographic integrity of applications relying on these libraries for secure r...

CVE-2025-66442

The Mbed TLS library through version 4.0.0 and TF-PSA-Crypto through version 1.0.0 are vulnerable to a compiler-induced timing side channel . This issue specifically affects RSA and CBC/ECB decryption operations and only occurs when using the LLVM select-optimize feature. No specific exploit deta...
