CVE-2016-10044 Open this link in a new tabHow to fix?
Upgrade Oracle:5 kernel-uek-debug to version 0:2.6.39-400.297.12.el5uek or higher.
This issue was patched in ELSA-2017-3637.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug package and not the kernel-uek-debug package as distributed by Oracle.
See How to fix? for Oracle:5 relevant fixed versions and status.
The aio_mount function in fs/aio.c in the Linux kernel before 4.7.7 does not properly restrict execute access, which makes it easier for local users to bypass intended SELinux W^X policy restrictions, and consequently gain privileges, via an io_setup system call.
