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 rpmsg_eptdev_write_iter() function in drivers/rpmsg/rpmsg_char.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering copy_from_iter_full() failures, aka CID-bbe692e349e2.
