CVE-2011-2689
CVSS v2.0
4.9
Média
| Vetor | AV:L/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 3.0-rc1
Description
The issue allows local users to cause a denial of service, resulting in a system crash, by arranging for all resource groups to have too little free space. This is due to the gfs2 fallocate function in fs/gfs2/file.c not ensuring that the size of a chunk allocation is a multiple of the block size.
Recommendations
For Linux kernel versions prior to 3.0-rc1, update to version 3.0-rc1 or later to resolve the issue. As a temporary workaround, consider restricting access to the gfs2 fallocate function to minimize the risk of exploitation.
Correção
