57) Input validation error

EUVDB-ID: #VU83440

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-5158

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

The vulnerability allows a malicious guest to perform a denial of service (DoS) attack.
