1) Improper Authentication

EUVDB-ID: #VU61608

Risk: Medium

CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-0547

CWE-ID: CWE-287 - Improper Authentication

2) Input validation error

EUVDB-ID: #VU66476

Risk: Medium

CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-36946

CWE-ID: CWE-20 - Improper input validation

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input within the nfqnl_mangle() function in net/netfilter/nfnetlink_queue.c in the Linux kernel when processing IPv6 packets. A remote attacker can send specially crafted packets to the system and perform a denial of service (DoS) attack.

3) Input validation error

EUVDB-ID: #VU66881

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
