CVE-2015-8787 describes a critical denial-of-service vulnerability in the Linux kernel's nf_nat_redirect_ipv4 function, affecting versions prior to 4.4. An unauthenticated remote attacker can exploit this flaw by sending specific IPv4 packets to an incompletely configured interface, leading to a NULL pointer dereference and system crash, with potential for further unspecified impact. This vulnerability carries a CVSS score of 9.8 (Critical) due to its network-based attack vector, low attack complexity, and high impact on availability, integrity, and confidentiality. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
