Summary

A vulnerability in the Linux kernel 2.6 before version 2.6.11 allows a local user to gain elevated privileges by injecting mouse or keyboard events into other user sessions. The issue is due to missing access restrictions on the N_MOUSE line discipline for a TTY.

Risk Assessment

An attacker can take control of other users' sessions, leading to privilege escalation and potential compromise of system confidentiality and integrity.
