|Bugzilla:||652957: CVE-2010-4163 CVE-2010-4668 kernel: panic when submitting certain 0-length I/O requests|
The MITRE CVE dictionary describes this issue as:
The blk_rq_map_user_iov function in block/blk-map.c in the Linux kernel before 126.96.36.199 allows local users to cause a denial of service (panic) via a zero-length I/O request in a 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.
