Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU88228

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-46842

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The 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.

Mitigation

Update the affected package xen to the latest version.

2) Improper locking

EUVDB-ID: #VU94499

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-2024-31143

CWE-ID: CWE-667 - Improper Locking

Exploit availability: No

Description

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

The vulnerability exists due to double unlock in x86 guest IRQ handling. An optional feature of PCI MSI called "Multiple Message" allows a device to use multiple consecutive interrupt vectors. A malicious guest can crash the hypervisor.

Mitigation
