The vulnerability exists in Intel processors due to excessive data output when DirectPath I/O (PCI-Passthrough) is utilized. An attacker (both local and remote) with administrative access to a virtual machine that has an attached DirectPath I/O (PCI-Passthrough) device can obtain information stored in physical memory about the hypervisor or other virtual machines that reside on the same host.



Mitigation

Update the affected package the Linux Kernel to the latest version.

CVE-ID: CVE-2022-21180

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation in Memory Mapped I/O (MMIO) for some 14nm Client/Xeon E3 Intel® Processors. A local user can pass specially crafted input and perform a denial of service (DoS) attack in certain virtualized environments.

Mitigation

Update the affected package the Linux Kernel to the latest version.

19) Incorrect default permissions

EUVDB-ID: #VU63631

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-30594

CWE-ID: CWE-276 - Incorrect Default Permissions

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to mishandling seccomp permissions. A local user can bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag and escalate privileges on the system.

Mitigation

Update the affected package the Linux Kernel to the latest version.
