Name of the Vulnerable Software and Affected Versions: JFFS2 versions (affected versions not specified)

Description: The issue is related to the improper storage of permissions during inode creation or ACL setting when POSIX ACL support is enabled.

The problem is connected to "legacy modes" and an inconsistency between dentry permissions and inode permissions.
