Critical Security Flaws Uncovered Fourteen vulnerabilities in Linux and FreeBSD have paved the way for severe cyber attacks. These flaws allow root privilege escalation, container escapes, and virtual machine breaches. Functional exploits have already emerged for several of these severe flaws. Moreover, certain issues were disclosed before developers could issue appropriate patches. Researchers discovered multiple severe vulnerabilities within the Linux kernel.

TL;DR Researcher Hyunwoo Kim has published full details and proof-of-concept exploits for six Linux kernel vulnerabilities he calls "Infinity Core." Five of them lead to local privilege escalation and container escape, and one crashes the kernel. Upstream fixes exist, so admins should install patched kernels now. Why It Matters These bugs sit in core kernel code: timers, signals, memory management, futex, the scheduler and the SLAB allocator.
