--- title: "CVE-2016-7916\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2016-7916?format=md keywords: index, follow --- # CVE-2016-7916 Publication date 16 November 2016 Last updated 4 July 2026 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) ## Cvss 3 Severity Score **5.5 · Medium** [Score breakdown](https://ubuntu.com/security/CVE-2016-7916?format=md#impact-score) Toggle side navigation ## Description Race condition in the environ\_read function in fs/proc/base.c in the Linux kernel before 4.5.4 allows local users to obtain sensitive information from kernel memory by reading a /proc/\*/environ file during a process-setup time interval in which environment-variable copying is incomplete. ### From the Ubuntu Security Team It was discovered that a race condition existed in the procfs environ\_read function in the Linux kernel, leading to an integer underflow. A local attacker could use this to expose sensitive information (kernel memory).
