CVE-2025-49601

In MbedTLS 3.3.0 before 3.6.4, mbedtlslmsimportpublickey 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 mbedtlslmsimportpublickey allows context-dependent...

CVE-2025-49600

In MBedTLS, CVE-2025-49600 affects 3.3.0 to before 3.6.4, where mbedtls_lms_verify can accept forged Leighton-Micali Signatures in fault scenarios. The root cause is unchecked return values from internal Merkle-tree calls (create_merkle_leaf_value and create_merkle_internal_value) which can leave...

CVE-2025-49600

In MbedTLS 3.3.0 before 3.6.4, mbedtlslmsverify may accept invalid signatures if hash computation fails and internal errors go unchecked, enabling LMS Leighton-Micali Signature forgery in a fault scenario. Specifically, unchecked return values in mbedtlslmsverify allow an attacker who can induce ...

CVE-2025-49601

CVE-2025-49601 affects MbedTLS 3.3.0 through 3.6.3 (fixed in 3.6.4). The issue is in mbedtls_lms_import_public_key, which reads a 4-byte type indicator before validating the input size. If the input LMS public-key buffer is truncated to fewer than four bytes, this allows an out-of-bounds read, po...

PT-2025-28012

Name of the Vulnerable Software and Affected Versions: MbedTLS versions 3.3.0 through 3.6.3 Description: The issue allows an attacker to bypass LMS signature verification by reusing stale stack data, resulting in the acceptance of an invalid signature. This occurs when unchecked return values in...
