CVE-2016-0723 is a vulnerability of currently unknown severity. Race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel through 4.4.1 allows local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call.. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
