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 pcpu_embed_first_chunk function in mm/percpu.c in the Linux kernel through 4.14.14 allows local users to obtain sensitive address information by reading dmesg data from a "pages/cpu" printk call.
