|Bugzilla:||652529: CVE-2010-4162 kernel: bio: integer overflow page count when mapping/copying user data|
The MITRE CVE dictionary describes this issue as:
Multiple integer overflows in fs/bio.c in the Linux kernel before 188.8.131.52 allow local users to cause a denial of service (system crash) via a crafted device ioctl to a SCSI device.
This issue did not affect the versions of Linux kernel as shipped with Red Hat
Enterprise Linux 4 and 5 as they did not backport the upstream commit c5dec1c3 that introduced the issue. This has been addressed in Red Hat Enterprise Linux 6 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0007.html and https://rhn.redhat.com/errata/RHSA-2011-0330.html.
