Public exploitAvailablePublished on Exploit-DB

The VT implementation (vt_ioctl.c) in Linux kernel 2.6.12, and possibly other versions including 2.6.14.4, allows local users to use the KDSKBSENT ioctl on terminals of other users and gain privileges, as demonstrated by modifying key bindings using loadkeys.

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.
