14) Information disclosure

EUVDB-ID: #VU64366

Risk: Low

CVSSv3.1: 5.2 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-21166

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows an attacker to gain access to potentially sensitive information.

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.

CVE-ID: CVE-2022-21499

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a local user to bypass implemented security restrictions.

The vulnerability exists due to improper access restrictions to the kernel debugger when booted in secure boot environments. A local privileged user can bypass UEFI Secure Boot restrictions.

Mitigation

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

17) Missing initialization of resource

EUVDB-ID: #VU61211

Risk: Low

CVSSv3.1: 3.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-24448

CWE-ID: CWE-909 - Missing initialization of resource

Exploit availability: No

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to missing initialization of resource within the fs/nfs/dir.c in the Linux kernel. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor.

Mitigation

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