Permissions, Privileges, and Access Controls in Linux kernel - CVE-2016-10044

Vulnerability identifier: #VU6642

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-2016-10044

CWE-ID: CWE-264

Exploitation vector: Local access

Exploit availability: No public exploit available

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

The vulnerability exists due to improper privilege management within the aio_mount() function in fs/aio.c. A local user can bypass SELinux W^X policy restrictions and execute arbitrary code with elevated privileges.
