CVE-2012-1090

CVE-2012-1090 REJECTED CVSS 5.5 MEDIUM

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."
