Public Exploits Released for Four Linux Kernel Flaws That Enable Local Root

A security researcher has made public exploit code for four vulnerabilities in the Linux kernel that allow a local user to gain root access. These flaws have been fixed by kernel maintainers in recent weeks. As a result, systems running the latest kernel version are not vulnerable. However, machines still using an older kernel version are at risk and should be updated to prevent exploitation. The release of the exploit code increases the risk for systems that have not been updated.
