mbedtls: CVE-2019-18222

Severity: Medium
Published: Jan 23, 2020, 5:15:00 PM UTC
Source: [NVD] · [CVE record]
EPSS: 0.34% · Oct 25, 2026

The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS through 2.19.1 does not reduce the blinded scalar before computing the inverse, which allows a local attacker to recover the private key via side-channel attacks.
