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 kernel in Apple iOS before 8 and Apple TV before 7 uses a predictable random number generator during the early portion of the boot process, which allows attackers to bypass certain kernel-hardening protection mechanisms by using a user-space process to observe data related to the random numbers.
