CWE ids for CVE-2022-2048

  • The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.
    Assigned by: nvd@nist.gov (Primary)
  • The product's resource pool is not large enough to handle peak demand, which allows an attacker to prevent others from accessing the resource by using a (relatively) large number of requests for resources.
    Assigned by: emo@eclipse.org (Secondary)
  • The product does not maintain or incorrectly maintains control over a resource throughout its lifetime of creation, use, and release.
    Assigned by: emo@eclipse.org (Secondary)
