CVE-2010-4078
Published: 29 November 2010
The sisfb_ioctl function in drivers/video/sis/sis_main.c in the Linux kernel before 2.6.36-rc6 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via an FBIOGET_VBLANK ioctl call.
From the Ubuntu Security Team
Dan Rosenberg discovered that the SiS video driver did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
