Vuln kernel pax
Description
This means that your system is vulnerable to stack overflow attacks. The kernel is not robust to the type of vulnerability. ASL includes a special kernel that is immune to these weaknesses. If you are getting a kernel weakness vulnerability alert on your system then you are not running a secure kernel like ASL.
This means your system is vulnerable to a whole class of attacks that can cause the entire system to become compromised.
Resolving This Vulnerability
You need to install the ASL kernel. ASL will install this by default, provided that you do not have kernel installs disabled on your system. If you do not have kernel installation disabled, then simply reboot your system into the secure ASL.
If you are not sure if you have kernel installation disabled, or if you have the ASL kernel installed, please see the kernel wiki article for guidance on checking your systems configuration to ensure you can install kernels, and how to install the kernel if you had your system configured to not allow kernels to be installed.
Notes for VPS Machines
Please note that VPS systems do not have their own kernel. So if you are using a VPS technology you will not be able to install any kernel on the system. VPS technologies share the hosts kernel, and the VPS will inherit the vulnerabilities in that kernel. If you do not control the host, we encourage you to report this vulnerability to your hosting provider and ask they fix their kernel. One way to do this is for them to install the secure ASL kernel on the host.
