CVE-2011-2689 is a vulnerability of currently unknown severity. The gfs2_fallocate function in fs/gfs2/file.c in the Linux kernel before 3.0-rc1 does not ensure that the size of a chunk allocation is a multiple of the block size, which allows local users to cause a denial of service (BUG and system crash) by arranging for all resource groups to have too little free space.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
