Linux Kernel 3.19 Security Vulnerability exposed Ubuntu 15.04 users should update it as soon as possible

Linux Kernel 3.19 has two security vulnerabilities! The first vulnerability may cause information leakage of Multi-device Linux Kernel drivers and may allow privileged access. Attackers can retrieve sensitive information from the Kernel. The second leakage is a Linux Kernel Virtual Machine Driver Vulnerability. This vulnerability does not properly describe the log files stored in the user space and allows attackers to perform DoS attacks.

At present, Canonical has released a USN-2752-1 Security Bulletin to explain the relevant issues, and in the CVE-2015-5697 and CVE-2015-6252 security tips to describe the details of these two kernel vulnerabilities. The two vulnerabilities discovered this time will affect other GNU/Linux operating systems. Therefore, we recommend that you read the above articles.

Note: These two Linux Kernel security vulnerabilities affect all Ubuntu 15.04 and Linux Kernel 3.19 users.

Canonical recommends that all Ubuntu 15.04 users update the kernel package as soon as possible and synchronize the software source to the latest version. Finally, we are prompted not to forget to restart the system after the update.
