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 sof_set_get_large_ctrl_data() function in sound/soc/sof/ipc.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering sof_get_ctrl_copy_params() failures, aka CID-45c1380358b1.
