  1. 11-Year Old Linux Kernel Local Privilege Escalation Flaw Discovered

New privilege-escalation vulnerability has been discovered in Linux kernel and affects major distro of the Linux operating system, including Redhat, Debian, OpenSUSE, and Ubuntu. Vulnerability is a use-after-free flaw in the way the Linux kernel’s “DCCP protocol implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket.” The DCCP double-free vulnerability could allow a local unprivileged user to alter the Linux kernel memory. This vulnerability does not provide any way for an outsider to break into your system in the first place, as it is not a remote code execution (RCE) flaw and require an attacker to have a local account access on the system to exploit the flaw.

Cyber Security Tips:  Vulnerability has already been patched in the mainline kernel. So, if you are an advanced Linux user, apply the patch and rebuild kernel yourself or you can wait until new patches release.
