CVE-2011-2689

Linux Kernel < 3.0 - Denial of Service via GFS2 Chunk Allocation

Title source: llm
STIX 2.1

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.
