1) Use of Uninitialized Variable (CVE-ID: CVE-2024-9355)

The vulnerability allows a remote attacker to weaken TLS encryption.

The vulnerability exists due to an uninitialized buffer length variable in the CGO bindings that intermittently return a zeroed buffer from (*boringHMAC).Sum() in FIPS mode.
