|Bugzilla:||631716: CVE-2010-3066 kernel: io_submit_one() NULL ptr deref|
The MITRE CVE dictionary describes this issue as:
The io_submit_one function in fs/aio.c in the Linux kernel before 2.6.23 allows local users to cause a denial of service (NULL pointer dereference) via a crafted io_submit system call with an IOCB_FLAG_RESFD flag.
This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 3 and 4 as they did not include support for eventfd in the
Async I/O (AIO) implementation. It did not affect the version of Linux kernel
as shipped with Red Hat Enterprise MRG as it has already had the fix to this
issue. This issue was addressed in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RHSA-2010-0839.html
