A fault injection attack on RAM via Rowhammer leads to ECDSA key disclosure.

Does this matter?
Lower severity and a low EPSS score (0.56%). Track it; it rarely justifies an emergency change on its own.
Description
An issue was discovered in wolfSSL before 5.5.0. A fault injection attack on RAM via Rowhammer leads to ECDSA key disclosure. Users performing signing operations with private ECC keys, such as in server-side TLS connections, might leak faulty ECC signatures. These signatures can be processed via an advanced technique for ECDSA key recovery. (In 5.5.0 and later, WOLFSSL_CHECK_SIG_FAULTS can be used to address the vulnerability.)
