Vulnerabilities in the algorithms used by Fuchsia to populate network protocol header fields, specifically the TCP ISN, TCP timestamp, TCP and UDP source ports, and IPv4/IPv6 fragment ID allow for these values to be guessed under circumstances

A bug exists where an attacker can read the kernel log through exposed Zircon kernel addresses without the required capability ZXRSRCKINDROOT. It is recommended to upgrade the Fuchsia kernel to 4.1.1 or greater.
