CVE-2011-2689

Priority
Description
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.
Ubuntu-Description
It was discovered that GFS2 did not correctly check block sizes. A local
attacker could exploit this to crash the system, leading to a denial of
service.
