Discussion
Linux Kernel CVE-2013-6763 Integer Overflow Vulnerability
The Linux kernel is prone to an integer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data.
Attackers can exploit this issue to execute arbitrary code with kernel privileges. Failed exploit attempts will likely crash the kernel, denying service to legitimate users.
Note: This issue was previously covered in BID 63512 (Linux Kernel CVE-2013-4511 Multiple Integer Overflow Vulnerabilities), but has been given its own record to better document it.
