Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU88228
Risk: Medium
CVSSv4.0: [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-46842
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a malicious guest to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of register values when invoking a hypercall. A malicious HVM or PVH guest can pass specially crafted input to the hypervisor and perform a denial of service (DoS) attack.
MitigationUpdate the affected package xen to the latest version.
