AI Summary
CISA added three actively exploited Linux kernel vulnerabilities to its Known Exploited Vulnerabilities catalog, with at least one rated critical, capable of enabling denial-of-service, memory disclosure, or memory modification. Federal agencies face mandatory patching deadlines under BOD 22-01, but the active exploitation status makes these urgent for all Linux-based infrastructure operators.
