CVE-2010-4077: Linux Kernel

Low severity, CVSS 1.9. EPSS: 1% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: up to and including 2.6.36.1
