Multiple TCP-based remote denial-of-service vulnerabilities have been uncovered in the Linux kernels by Netflix researchers. Exploitation would interrupt TCP connections and therefore streaming content flows to vulnerable Linux-based PCs (putting a crimp in binge-watching, for instance). Attackers could also disable connections to vulnerable internet of things gadgets, taking them offline. Netflix researchers found three related flaws in Linux kernel s handling of TCP networking. The most severe vulnerability (CVE-2019-11477), dubbed SACK Panic, impacts Linux kernels 2.29 versions and above.
