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-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-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-2026-34872

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...

GHSA-GVRJ-CJCH-728P Juju has Improper TLS Client/Server authentication and certificate verification on Database Cluster

Impact Any Juju controller since 3.2.0. An attacker with only route-ability to the target juju controller Dqlite cluster endpoint may join the Dqlite cluster, read and modify all information, including escalating privileges, open firewall ports etc. This is due to not checking the client...

PT-2026-29692

A vulnerability has been found in Cesanta Mongoose up to 7.20. This affects the function mg tls recv cert of the file mongoose.c of the component TLS 1.3 Handler. Such manipulation of the argument pubkey leads to heap-based buffer overflow. The attack may be launched remotely. The exploit has bee...

CVE-2026-34877

CVE-2026-34877 concerns Mbed TLS: versions 2.19.0 through 3.6.5 and 4.0.0 have insufficient protection of serialized SSL context or session structures. An attacker who can modify serialized data may induce memory corruption, leading to arbitrary code execution due to the Incorrect Use of Privileg...

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...

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...
