CVE-2010-4082

EPSS 0.4%

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.
