1) Use-after-free

EUVDB-ID: #VU28418

Risk: Low

CVSSv3.1: 6.4 [CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-19377

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local non-authenticated attacker to execute arbitrary code.

In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and unmounting can lead to a use-after-free in btrfs_queue_work in fs/btrfs/async-thread.c.

Mitigation

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

2) Protection Mechanism Failure

EUVDB-ID: #VU54455

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-2020-26541

CWE-ID: CWE-693 - Protection Mechanism Failure

Exploit availability: No

Description

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

17) 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.

18) Input validation error

EUVDB-ID: #VU64377

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

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.

CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-32250

CWE-ID: CWE-416 - Use After Free

Exploit availability: Yes

Description

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

The vulnerability exists due to a use-after-free incorrect NFT_STATEFUL_EXPR in net/netfilter/nf_tables_api.c in Linux kernel. A local user with ability to create user/net namespaces can execute arbitrary code with root privileges.
