37
FAUCET Score

CVE-2010-0437 describes a denial-of-service vulnerability in the Linux kernel before version 2.6.27, specifically within the ip6_dst_lookup_tail function. This flaw, triggered by improper handling of IPv6 TUN interfaces with numerous neighbors, can lead to a NULL pointer dereference and system crash (OOPS). With a CVSS score of 7.8, it is considered highly severe, allowing unauthenticated attackers to cause a complete denial of service with low attack complexity. While not on the CISA KEV catalog, a public exploit (EDB-33635) exists, though there is no evidence of active exploitation or significant community discussion.
