A set of four vulnerabilities in the OpenPrinting CUPS printing stack (CVE-2024-47176, CVE-2024-47076, CVE-2024-47175, CVE-2024-47177) affecting many major Linux distributions was disclosed along with proof-of-concept exploit code; exploitation requires the CUPS services to be enabled and reachable, limiting widespread impact. Remediation options include disabling/removing cups-browsed, updating CUPS packages, or blocking relevant network traffic; researchers noted a leaked report and public exposure of at least ~75,000 CUPS daemons.
