JLSEC-2026-467 Mbed TLS serialized session data is not cryptographically protected
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...
JLSEC-2026-465 Mbed TLS may use a low entropy PRNG seed
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...
JLSEC-2026-463 Mbed TLS timing side channel in RSA and CBC/ECB decryption
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...
JLSEC-2026-464 Mbed TLS might use cloned PSA random generator states

JLSEC-2026-466 Mbed TLS peer can force the FFDH shared secret into a small set of values
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...

An issue was discovered in Mbed TLS 3.x before 3.6.6. An out-of-bounds read vulnerability in mbedtls_ccm_finish() in library/ccm.c allows attackers to obtain adjacent CCM context data via invocation of the multipart CCM API with an oversized tag_len parameter. This is caused by missing validation of the tag_len parameter against the size of the internal 16-byte authentication buffer. The issue affects the public multipart CCM API in Mbed TLS 3.x, where mbedtls_ccm_finish() can be invoked directly by applications. In Mbed TLS 4.x versions prior to the fix, the same missing validation exists in the internal implementation; however, the function is not exposed as part of the public API. Exploitation requires application-level invocation of the multipart CCM API.

JLSEC-2026-417 libcurl did not check the server certificate of TLS connections done to a host specified as an IP...
libcurl did not check the server certificate of TLS connections done to a host specified as an IP address, when built to use mbedTLS. libcurl would wrongly avoid using the set hostname function when the specified hostname was given as an IP address, therefore completely skipping the certificate...
