CVE-2017-7472

Published: 11 May 2017

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.

From the Ubuntu security team

Eric Biggers discovered a memory leak in the keyring implementation in the Linux kernel. A local attacker could use this to cause a denial of service (memory consumption).
