Waratek protection

Mitigation candidate

A kind of vulnerability Waratek's rules address, with exploit code published or exploitation reported. No rule exists and none is planned yet. The decision below says what we found to build a rule from.

  • Protection none
  • Action unverified
  • Review automated Inferred
  • Record active
Decided by A reference pointing at the upstream fix: a commit, a PR, a Red Hat bug
Finding A reference points at an upstream fix (redhat-cve tier): https://access.redhat.com/security/cve/CVE-2022-21449. That makes this CVE a candidate for an ARMR patch rule — it is the kind of defect ARMR can address, and there is a fix to work from. No rule exists and none is scheduled: writing one means reading the linked change and finding a hook point ARMR can express it at, which may turn out not to exist.
Candidate fix https://access.redhat.com/security/cve/CVE-2022-21449 : a Red Hat CVE page: the weakest kind, naming no commit, though it shows Red Hat has looked at the CVE
