CVE-2011-4062

CVE-2011-4062 describes a buffer overflow vulnerability in the FreeBSD kernel (versions 7.3 through 9.0-RC1) that can be triggered by a local user. This flaw, specifically in the bind system call when processing a long pathname for a UNIX socket, could lead to a denial of service (system panic) or potentially privilege escalation. With a CVSS score of 7.2, it is considered highly severe due to its local attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. While not listed on the KEV catalog or Hot List, a proof-of-concept exploit exists on ExploitDB, though there is no evidence of active exploitation or significant community discussion.
