Description

This security bulletin contains information about 1 vulnerability.


1) Improper validation of integrity check value (CVE-ID: CVE-2026-75803)

CWE-ID: CWE-354 - Improper Validation of Integrity Check Value

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a local user to bypass integrity checks.

The vulnerability exists due to improper validation of integrity check value in EVP_Cipher() for ChaCha20-Poly1305 and AES-OCB when decrypting an empty ciphertext. A local user can provide a forged empty-ciphertext message with a supplied authentication tag to bypass integrity checks.

The issue occurs when applications use EVP_Cipher() and expect a successful return value to indicate that the AEAD tag was verified.
