CVE-2013-6282 · Severity: critical · CVSS 8.8 · Exploited in the wild · Published 2022-09-15

The get_user and put_user API functions in the Linux kernel on ARM v6k and v7 platforms fail to properly validate addresses. This allows a local attacker to read or modify arbitrary kernel memory locations via a crafted application, potentially leading to privilege escalation.
