CVE-2020-0465

A flaw was found in the Linux kernel’s multi-touch input system. An out-of-bounds write triggered by a use-after-free issue could lead to memory corruption or possible privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

As the multitouch module will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions:

echo "install hid-multitouch /bin/true" >> /etc/modprobe.d/disable-hid-multitouch.conf

The system may need to be restarted if the hid-multitouch module is loaded. In most circumstances, a kernel modules will be unable to be unloaded while in use.

If the system requires this module to work correctly, this mitigation may not be suitable.
