CVE-2013-6282
Published: September 15, 2022
Official Description
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.
CISA KEV Advisory
Linux Kernel Improper Input Validation Vulnerability
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.
Apply updates per vendor instructions.
Risk Analysis
The Linux kernel's get_user and put_user API functions on ARM v6k/v7 platforms fail to validate target addresses, allowing applications to read and write kernel memory, which can lead to privilege escalation. The high EPSS score of 0.67650 indicates a high likelihood of exploitation, and its presence in CISA's KEV confirms active exploitation.
This vulnerability is actively exploited in the wild, as confirmed by its inclusion in CISA's KEV. Exploitation requires a local application.
Linux kernel users on ARM v6k/v7 platforms should update their systems to a patched kernel version. Ensure that only trusted applications are run on these systems.
Technical Analysis
CVE-2013-6282 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2013-6282 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
