New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

The USB subsystem in the Linux kernel before 2.6.36-rc5 does not properly initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to TIOCGICOUNT ioctl calls, and the (1) mos7720_ioctl function in drivers/usb/serial/mos7720.c and (2) mos7840_ioctl function in drivers/usb/serial/mos7840.c.
