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

A memory leak in the predicate_parse() function in kernel/trace/trace_events_filter.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-96c5c6e6a5b6.
