CVE-2010-4077 is a vulnerability of currently unknown severity. The ntty_ioctl_tiocgicount function in drivers/char/nozomi.c in the Linux kernel 2.6.36.1 and earlier does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call.. EPSS estimates a 1.04% chance of exploitation in the next 30 days.
