Base vector

AV:L/AC:L/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.7.6

Description The issue is related to the xfs buf find function in fs/xfs/xfs buf.c, which does not validate block numbers. This allows local users to cause a denial of service, resulting in a NULL pointer dereference and system crash, or possibly have other unspecified impacts. This can be achieved by mounting an XFS filesystem containing a metadata inode with an invalid extent map.

Recommendations For Linux kernel versions prior to 3.7.6, update to version 3.7.6 or later to resolve the issue.
