|Bugzilla:||648671: CVE-2010-4082 kernel: drivers/video/via/ioctl.c: reading uninitialized stack memory|
The MITRE CVE dictionary describes this issue as:
The viafb_ioctl_get_viafb_info function in drivers/video/via/ioctl.c in the Linux kernel before 2.6.36-rc5 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a VIAFB_GET_INFO ioctl call.
This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 3, 4, and 5 as they did not include support for VIA UniChrome (Pro) and Chrome9 graphics boards.
