CVE-2005-0839
Linux kernel 2.6 before 2.6.11 does not restrict access to the N_MOUSE line discipline for a TTY, which allows local users to gain privileges by injecting mouse or keyboard events into other user sessions.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
