kernel: concurrency use-after-free between drm_setmaster_ioctl and drm_mode_getresources

A use-after-free vulnerability was found in drmleaseheld in drivers/gpu/drm/drmlease.c in the Linux kernel due to a race problem. This flaw allows a local user privilege attacker to cause a denial of service DoS or a kernel information leak...
