#VU95698 Security restrictions bypass in Linux kernel - CVE-2015-1328
Published: November 28, 2016 / Updated: January 15, 2025
Linux kernel
Linux Foundation
Description
The vulnerability allows a local user to execute arbitrary code.
The overlayfs implementation in the linux (aka Linux kernel) package before 3.19.0-21.21 in Ubuntu through 15.04 does not properly check permissions for file creation in the upper filesystem directory, which allows local users to obtain root access by leveraging a configuration in which overlayfs is permitted in an arbitrary mount namespace.
