Memory corruption in Linux kernel - CVE-2017-1000253

Vulnerability identifier: #VU8638

CSH Severity: Low

CVSS v4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2017-1000253

CWE-ID: CWE-119

Exploitation vector: Local access

Exploit availability: The vulnerability is being exploited in the wild

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to an error when loading of Executable and Linkable Format (ELF) executables. A local user can create a specially crafted ELF binary, trigger memory corruption and execute arbitrary code on the vulnerable system with root privileges.
