--- title: "CVE-2015-7885\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-2015-7885?format=md keywords: index, follow --- # CVE-2015-7885 Publication date 23 October 2015 Last updated 4 July 2026 --- Ubuntu priority **Low** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) ## Cvss 3 Severity Score **2.3 · Low** [Score breakdown](https://ubuntu.com/security/CVE-2015-7885?format=md#impact-score) Toggle side navigation ## Description The dgnc\_mgmt\_ioctl function in drivers/staging/dgnc/dgnc\_mgmt.c in the Linux kernel through 4.3.3 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory via a crafted application. ### From the Ubuntu Security Team It was discovered that the driver for Digi Neo and ClassicBoard devices did not properly initialize data structures. A local attacker could use this to obtain sensitive information from the kernel.
