CVE-2015-6252
Published: 19 August 2015
The vhost_dev_ioctl function in drivers/vhost/vhost.c in the Linux kernel before 4.1.5 allows local users to cause a denial of service (memory consumption) via a VHOST_SET_LOG_FD ioctl call that triggers permanent file-descriptor allocation.
From the Ubuntu security team
Marc-André Lureau discovered that the vhost driver did not properly release the userspace provided log file descriptor. A privileged attacker could use this to cause a denial of service (resource exhaustion).
