|Bugzilla:||633140: CVE-2010-3298 kernel: drivers/net/usb/hso.c: prevent reading uninitialized memory|
The MITRE CVE dictionary describes this issue as:
The hso_get_count function in drivers/net/usb/hso.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 TIOCGICOUNT 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 support USB Option High Speed Mobile Devices. This was addressed in Red Hat Enterprise Linux Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2010-0771.html.
