Name of the Vulnerable Software and Affected Versions Linux kernel version 2.6.37

Description The issue is related to an integer signedness error in the btrfs ioctl space info function, which allows local users to cause a denial of service, specifically a heap-based buffer overflow, or possibly have other unspecified impacts. This can be achieved by using a crafted slot value.

Recommendations For Linux kernel version 2.6.37, consider applying a patch to fix the integer signedness error in the btrfs ioctl space info function as a permanent solution. As a temporary workaround, restrict access to the btrfs ioctl space info function to minimize the risk of exploitation.
