CVE-2016-4482  (opens in a new tab)
CWE-665  (opens in a new tab)

How to fix?

There is no fixed version for RHEL:6 perf.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The proc_connectinfo function in drivers/usb/core/devio.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via a crafted USBDEVFS_CONNECTINFO ioctl call.
