CVE-2009-3001

Status: ModifiedMedium (4.9)—💥 Exploit

The llc_ui_getname function in net/llc/af_llc.c in the Linux kernel 2.6.31-rc7 and earlier does not initialize a certain data structure, which allows local users to read the contents of some kernel memory locations by calling getsockname on an AF_LLC socket.

CVSS

Version: 2.0
Vector: AV:L/AC:L/Au:N/C:C/I:N/A:N
Base score: 4.9

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 1.02%
Percentile among all scored CVEs: 63
Score date: 10/14/2026

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.
