CVE-2017-7472MEDIUM
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 KEYS subsystem in the Linux kernel before 4.10.13 allows local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls.
