CVE-2013-6282

CVE-2013-6282 is a high-severity (CVSS 8.8) vulnerability in Linux Kernel. CISA added it to the Known Exploited Vulnerabilities catalog on September 15, 2022, which means exploitation in the wild has been confirmed; US federal agencies had to remediate it by October 6, 2022. CISA does not currently list it as used in ransomware campaigns. Linux has 32 vulnerabilities in the KEV catalog, 2 of them linked to ransomware.

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.
