Netfilter is a framework in the Linux kernel that helps with network tasks like filtering packets, translating network addresses, and translating ports.
The vulnerability was fixed in January 2024, but it is currently unclear how the flaw was exploited in the attacks.
A new security flaw (CVE-2024-24919, CVSS score: 7.5) has been added to the KEV catalog. It affects Check Point network gateway security products, allowing attackers to read sensitive information on Internet-connected Gateways with remote access VPN or mobile access enabled.
Federal agencies should apply the latest fixes by June 20, 2024, to protect their networks from potential threats related to CVE-2024-1086 and CVE-2024-24919.
