kernel is vulnerable to denial of service (DoS). The vulnerability exists as a flaw was found in the way space was allocated in the Linux kernel’s Global File System 2 (GFS2) implementation. If the file system was almost full, and a local, unprivileged user made an fallocate() request, it could result in a denial of service. Note: Setting quotas to prevent users from using all available disk space would prevent exploitation of this flaw.
