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

arch/arm64/mm/dma-mapping.c in the Linux kernel before 4.0.3, as used in the ION subsystem in Android and other products, does not initialize certain data structures, which allows local users to obtain sensitive information from kernel memory by triggering a dma_mmap call.
