CVSSv3.1: 6.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-1353
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in the pfkey_register function in net/key/af_key.c in the Linux kernel. A local user can gain unauthorized access to kernel memory, leading to a system crash or a leak of internal kernel information.
MitigationInstall updates from vendor's website.
