NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-livepatch-devel package and not the kernel-default-livepatch-devel package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

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.
