Last modified Jun 17, 2026

CVE-2016-10044 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.30% chance of exploitation in the next 30 days.
