CVE-2021-4037

Опубликовано: 16 сент. 2021
Источник: redhat
CVSS3: 4.4

Описание

A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not. This vulnerability is similar to the previous CVE-2018-13405 and adds the missed fix for the XFS.

The Impact is Moderate, because if no configuration problems with the system, then unlikely higher impact than unauthorized read access.
