CVE-2015-7885

Published: 23 October 2015

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.

Priority

Low

CVSS 3 base score: 2.3
