CVE-2020-0465: Input Validation

Published Dec 1, 2020
·
Updated

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.

Other sources

Google Android could allow a local attacker to gain elevated privileges on the system, caused by an out-of-bounds write in various methods of hid-multitouch.c. By executing a specially-crafted program, an attacker could exploit this vulnerability to escalate privileges.

— IBM

In hidoutputreport of hid-core.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
