CVE-2010-4075
Published: 29 November 2010
The uart_get_count function in drivers/serial/serial_core.c in the Linux kernel before 2.6.37-rc1 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.
From the Ubuntu security team
Dan Rosenberg discovered that multiple terminal ioctls did not correctly initialize structure memory. A local attacker could exploit this to read portions of kernel stack memory, leading to a loss of privacy.
