Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.3

The issue is related to errors in handling the

For Linux kernel versions prior to 4.3, update to version 4.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the
mmap min addr variable to minimize the risk of exploitation.Correção
Use of Uninitialized Resource
