CISA Known Exploited Vulnerability

Linux Kernel Improper Input Validation Vulnerability — Linux Kernel

The get_user and put_user API functions of the Linux kernel fail to validate the target address when being used on ARM v6k/v7 platforms. This allows an application to read and write kernel memory which could lead to privilege escalation.

CWE-20

Description

The (1) get_user and (2) put_user API functions in the Linux kernel before 3.5.5 on the v6k and v7 ARM platforms do not validate certain addresses, which allows attackers to read or modify the contents of arbitrary kernel memory locations via a crafted application, as exploited in the wild against Android devices in October and November 2013.

Affected configurations

• linux linux kernel (< 3.2.54) • linux linux kernel (>= 3.3 < 3.4.12) • linux linux kernel (>= 3.5 < 3.5.5)
