AlienVault OTX Vulnerabilities

AlienVault OTX Malware

The IPv6 implementation in the Linux kernel before 6.3 has a net/ipv6/route.c max_size threshold that can be consumed easily, e.g., leading to a denial of service (network is unreachable errors) when IPv6 packets are sent in a loop via a raw socket.

CVE-2023-52340 is a denial of service vulnerability found in the IPv6 networking stack of the Linux kernel versions prior to 6.3. The issue arises from the max_size threshold in the net/ipv6/route.c source file, which governs the maximum size of certain routing-related data structures. An attacker can exploit this by sending IPv6 packets in a continuous loop through a raw socket, rapidly consuming the max_size resource. This resource exhaustion causes the kernel to fail in processing legitimate IPv6 packets, resulting in network unreachable errors and effectively a denial of service condition. The vulnerability is classified under CWE-400 (Uncontrolled Resource Consumption). It requires no privileges or user interaction, and can be triggered remotely by an unauthenticated attacker with network access. The CVSS v3.1 score is 7.5 (high), reflecting the ease of exploitation and the significant impact on availability, although confidentiality and integrity remain unaffected. No patches were linked at the time of publication, but upgrading to Linux kernel 6.3 or later is expected to resolve the issue. The vulnerability is particularly concerning for environments heavily reliant on IPv6 and Linux-based systems, including cloud providers, data centers, and enterprise networks.
