CISA SSVC: Attend at low or medium mission impact; Act at high (mission-essential systems).
Action: No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation sooner than your standard update timelines at low or medium mission impact and as soon as possible at high, and watch the vendor's advisory for the fix.
