Multiple vulnerabilities in Dell Networking MX Series Switches

1) Memory leak

EUVDB-ID: #VU64079

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2022-1012

CWE-ID:

Exploit availability:

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient randomization in the net/ipv4/tcp.c when calculating port offsets in Linux kernel cause by small table perturb size. A remote attacker can cause memory leak and gain access to sensitive information.

Mitigation

Install update from vendor's website.

2) Use of insufficiently random values

EUVDB-ID: #VU64943

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2022-32296

CWE-ID:

Exploit availability:

Description

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

The vulnerability exists due to Linux kernel allowing TCP servers to identify clients by observing what source ports are used. A local user can gain unauthorized access to sensitive information on the system.

Mitigation

3) Information disclosure

EUVDB-ID: #VU64364

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2022-21123

CWE-ID:

Exploit availability:

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

Install update from vendor's website.
