How to fix?

Upgrade Alpine:3.20 mbedtls to version 2.7.0-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mbedtls package and not the mbedtls package as distributed by Alpine. See How to fix? for Alpine:3.20 relevant fixed versions and status.

In ARM mbed TLS before 2.7.0, there is a bounds-check bypass through an integer overflow in PSK identity parsing in the ssl_parse_client_psk_identity() function in library/ssl_srv.c.
