If the input exceeds this limit, the tool\nsilently truncates to the first 16MB and continues without signaling an error,\ncontrary to what the documentation states. This creates an integrity gap where\ntrailing bytes can be modified without detection if both signing and\nverification are performed using the same affected codepath.\nThe issue affects only the command-line tool behavior. Verifiers that process\nthe full message using library APIs will reject the signature, so the risk\nprimarily affects workflows that both sign and verify with the affected\n'openssl dgst' command. Streaming digest algorithms for 'openssl dgst' and\nlibrary users are unaffected.\nThe FIPS modules in 3.5 and 3.6 are not affected by this issue, as the\ncommand-line tools are outside the OpenSSL FIPS module boundary.\nOpenSSL 3.5 and 3.6 are vulnerable to this issue.\nOpenSSL 3.4, 3.3, 3.0, 1.1.1 and 1.0.2 are not affected by this issue.",

It provides no remote attack surface, no privilege escalation, and no confidentiality or availability impact, and the OpenSSL 3.5/3.6 FIPS modules are not affected. Given these constraints and its CLI-only scope, this CVE can be safely deprioritized in managed enterprise VM/server environments.",
