Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Processor optimization removal or modification of security-critical code

EUVDB-ID: #VU88374

Risk: Medium

CVSSv4.0: 7.6 [CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:U/U:Green]

CVE-ID: CVE-2024-2201

CWE-ID: CWE-1037 - Processor optimization removal or modification of security-critical code

Exploit availability: No

Description

The vulnerability allows a malicious guest to escalate privileges on the system.

The vulnerability exists due to native branch history injection on x86 systems. A malicious guest can infer the contents of arbitrary host memory, including memory assigned to other guests and compromise the affected system.

Mitigation

Update the affected package xen to the latest version.

2) Improper locking

EUVDB-ID: #VU94499

Risk: Medium

CVSSv4.0: 2.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:H/E:U/U:Green]

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

Update the affected package xen to the latest version.
