Cleartext transmission of sensitive information in OpenSSL - CVE-2025-69418

Vulnerability identifier: #VU122081

CSH Severity: Low

CVSS v4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2025-69418

CWE-ID: CWE-319

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to the trailing 1-15 bytes of a message may be exposed in cleartext on encryption and are not covered by the authentication tag. When using the low-level OCB API directly with AES-NI or other hardware-accelerated code paths, inputs whose length is not a multiple of 16 bytes can leave the final partial block unencrypted and unauthenticated. A remote attacker can intercept traffic and gain access to potentially sensitive information.
