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 bluetooth subsystem in the Linux kernel before 3.0-rc4 does not properly initialize certain data structures, which allows local users to obtain potentially sensitive information from kernel memory via a crafted getsockopt system call, related to (1) the l2cap_sock_getsockopt_old function in net/bluetooth/l2cap_sock.c and (2) the rfcomm_sock_getsockopt_old function in net/bluetooth/rfcomm/sock.c.
