CVE-2011-4062

Status: ModifiedHigh (7.2)—💥 Exploit

Buffer overflow in the kernel in FreeBSD 7.3 through 9.0-RC1 allows local users to cause a denial of service (panic) or possibly gain privileges via a bind system call with a long pathname for a UNIX socket.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
