CVE-2020-14331

Priority
Description
A flaw was found in the Linux kernel’s implementation of the invert video
code on VGA consoles when a local attacker attempts to resize the console,
calling an ioctl VT_RESIZE, which causes an out-of-bounds write to occur.
This flaw allows a local user with access to the VGA console to crash the
system, potentially escalating their privileges on the system. The highest
threat from this vulnerability is to data confidentiality and integrity as
well as system availability.
Notes
amurrayCONFIG_VGACON_SOFT_SCROLLBACK is required to be enabled for this to be exploitable. This config option is disabled in Ubuntu kernel configs.
