Denial of Service Vulnerability in gfs2_fallocate Function

CVE-2011-2689 · MEDIUM Severity

AV:L/AC:L/AU:N/C:N/I:N/A:C

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.
