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 z90crypt_unlocked_ioctl function in the z90crypt driver in the Linux kernel 2.6.9 does not perform a capability check for the Z90QUIESCE operation, which allows local users to leverage euid 0 privileges to force a driver outage.
