Linux · Linux Kernel · CVE-2010-2070
**Name of the Vulnerable Software and Affected Versions**
Xen versions 3.4 through 4.0
Linux kernel version 2.6.18
**Description**
The issue allows local users to cause a denial of service and modify the user mask of the PSR, effectively turning on BE. This can be achieved by exploiting a fault in the `faults.c` file when running on IA-64 architectures.
**Recommendations**
For Xen versions 3.4 through 4.0, update to a version that includes the fix for this issue.
For Linux kernel version 2.6.18, consider applying a patch or updating to a newer version that addresses this problem.
As a temporary workaround, consider restricting access to the `faults.c` file to minimize the risk of exploitation.
