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 fastrpc_dma_buf_attach() function in drivers/misc/fastrpc.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering dma_get_sgtable() failures, aka CID-fc739a058d99.
