Linux Distros Unpatched Vulnerability : CVE-2025-40779

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - If a DHCPv4 client sends a request with some specific options, and Kea fails to find an appropriate subnet for the client, the kea-dhcp4 process will abort with...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from netlink not properly handling memory limits during unicast, which could lead to an infinite retry loop...

SUSE CVE-2025-40779

If a DHCPv4 client sends a request with some specific options, and Kea fails to find an appropriate subnet for the client, the kea-dhcp4 process will abort with an assertion failure. This happens only if the client request is unicast directly to Kea; broadcast messages do not cause the problem...

CVE-2025-40779

A vulnerability was found in Kea. When an attacker who is an existing client with an assigned IP sends a crafted unicast packet directly to the server's IP and Kea cannot find any subnets that match that client's credentials, the server crashes causing a Denial of Service via assertion/NULL-path...
