Description

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

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.
