Mbed TLS versions 2.19.0 through 3.6.5 and 4.0.0 allow remote code execution through memory corruption when attackers modify serialized SSL context or session structures. The vulnerability stems from insufficient validation of deserialized data, enabling arbitrary code execution on systems using affected versions. CISA KEV status and active exploitation data not confirmed in provided intelligence.
A security vulnerability in Mbed TLS before 3.6.4 (CVSS 4.8). Remediation should follow standard vulnerability management procedures. Vendor patch is available.
Mbed TLS before 3.6.4 has a race condition in AESNI detection if certain compiler optimizations occur. An attacker may be able to extract an AES key from a multithreaded program, or perform a GCM forgery.
In MbedTLS 3.3.0 before 3.6.4, mbedtls_lms_import_public_key does not check that the input buffer is at least 4 bytes before reading a 32-bit field, allowing a possible out-of-bounds read on truncated input. Specifically, an out-of-bounds read in mbedtls_lms_import_public_key allows context-dependent attackers to trigger a crash or limited adjacent-memory disclosure by supplying a truncated LMS (Leighton-Micali Signature) public-key buffer under four bytes. An LMS public key starts with a 4-byte type indicator. The function mbedtls_lms_import_public_key reads this type indicator before validating the size of its input.
