Linux kernel is vulnerable to privilege escalation vulnerability. This exists in the function inode_init_owner of the file fs/inode.c. Local users could create files with an unintended group ownership and SGID permission bits set, when a directory is SGID and belongs to a certain group and is writable by an individual who is not in this group causing an excessive permission grant issue.
