Description
vcs_write in drivers/tty/vt/vc_screen.c in the Linux kernel through 5.3.13
does not prevent write access to vcsu devices, aka CID-0c9acb1af77a.
Ubuntu-Description
Or Cohen discovered that the virtual console subsystem in the Linux kernel
did not properly restrict writes to unimplemented vcsu (unicode) devices. A
local attacker could possibly use this to cause a denial of service (system
crash) or have other unspecified impacts.
