CVE-2026-1677
Zephyr sockets created with IPPROTOTLS13 can still negotiate a TLS 1.2 connection when both TLS versions are enabled in Kconfig, because the socket-level protocol selection is not propagated to mbedTLS e.g. via mbedtlssslconfmintlsversion. The ClientHello advertises both versions and the peer can...
Astra Linux – Vulnerability in mbedtls
A issue was discovered in Arm Mbed TLS prior to version 2.23.0. Due to a side channel in modular exponentiation, an RSA private key used in a secure enclave could be disclosed...
Astra Linux – Vulnerability in mbedtls
A timing side channel in mbedtlsssldecryptbuf in library/sslmsg.c in Trusted Firmware Mbed TLS from version 2.23.0 allows an attacker to obtain secret key information. This issue affects the CBC mode, as it involves a calculated time difference based on the padding length...
Astra Linux – Vulnerability in mbedtls
In Arm Mbed TLS before version 2.19.0, and Arm Mbed Crypto before version 2.0.0, when deterministic ECDSA is enabled, an RNG with insufficient entropy is used for blinding. This may allow an attacker to recover a private key through side-channel attacks if a victim signs the same message multiple...
Astra Linux – Vulnerability in mbedtls
A vulnerability was discovered in Mbed TLS before versions 2.28.1 and 3.x, prior to 3.2.0. In some configurations, an unauthenticated attacker can send an invalid ClientHello message to a DTLS server, causing a heap-based buffer overflow of up to 255 bytes. This can lead to a server crash or,...

This update for ovmf fixes the following issues - CVE-2026-25833: mbedtls: buffer underflow in x509inetptonipv6 bsc1261476. - CVE-2026-25834: mbedtls: Algorithm downgrade vulnerability bsc1261477. - CVE-2026-25835: mbedtls: PSA random generator cloning bsc1261478. - CVE-2026-34874: mbedtls: NULL...
CVE-2026-1677 net: TLS 1.2 connections allowed on TLS 1.3 sockets
Zephyr sockets created with IPPROTOTLS13 can still negotiate a TLS 1.2 connection when both TLS versions are enabled in Kconfig, because the socket-level protocol selection is not propagated to mbedTLS e.g. via mbedtlssslconfmintlsversion. The ClientHello advertises both versions and the peer can...
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-2026-463 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-2026-465 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-2026-466 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...
JLSEC-2026-464 Mbed TLS might use cloned PSA random generator states
Mbed TLS before 3.6.6 and TF-PSA-Crypto before 1.1.0 misuse seeds in a Pseudo-Random Number Generator PRNG...
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...
