CVSS 6.5 MEDIUM
A flaw was found in HTTP/2. An attacker can request a large amount of data by manipulating window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this queue can consume excess CPU, memory, or both, leading to a denial of service. The highest threat from this vulnerability is to system availability.
