What to do
CISA required actionApply remediations or mitigations per vendor instructions or discontinue use of the product if remediation or mitigations are unavailable.
US federal civilian agencies must remediate by (21 days after listing) under BOD 22-01. Everyone else: that deadline is a sensible upper bound, not a target. Vendor guidance and the NVD record are linked under Source above.
