CVE-2010-4078

Publication date 29 November 2010

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

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.
