CVE-2001-1185

Status: ModifiedMedium (6.2)—💥 Exploit

Some AIO operations in FreeBSD 4.4 may be delayed until after a call to execve, which could allow a local user to overwrite memory of the new process and gain privileges.

CVSS

Version: 2.0
Vector: AV:L/AC:H/Au:N/C:C/I:C/A:C
Base score: 6.2

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.81%
Percentile among all scored CVEs: 56
Score date: 10/7/2026

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.
