CVE-2013-4247 is an off-by-one error in the Linux kernel's CIFS filesystem, specifically affecting versions before 3.9.6. This vulnerability allows remote attackers to trigger a denial of service (memory corruption and system crash) by manipulating DFS share mount operations with unexpected referral name lengths. With a CVSS score of 7.8 (High), it presents a critical risk due to its network-based attack vector and low attack complexity, leading to a complete loss of availability. There is currently no evidence of active exploitation, no public exploit code available (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage.
