Описание
The cifs_lookup function in fs/cifs/dir.c in the Linux kernel before 3.2.10 allows local users to cause a denial of service (OOPS) via attempted access to a special file, as demonstrated by a FIFO.
Отчет
This issue did not affect the Linux kernel as shipped with Red Hat Enterprise Linux 4 and 5 as they did not backport the commit a6ce4932fbdbcd8f8e8c6df76812014351c32892 that introduced this issue. This issue did not affect the Linux kernel as shipped with Red Hat Enterprise MRG 2. This has been addressed in Red Hat Enterprise Linux 6 via https://rhn.redhat.com/errata/RHSA-2012-0481.html.

The cifs_lookup function in fs/cifs/dir.c in the Linux kernel before 3.2.10 allows local users to cause a denial of service (OOPS) via attempted access to a special file, as demonstrated by a FIFO. "The cifs code will attempt to open files on lookup under certain circumstances. What happens though if we find that the file we opened was actually a FIFO or other special file? Currently, the open filehandle just ends up being leaked leading to a dentry refcount mismatch and oops on umount."
