** Description changed: - From the CVE request on oss-security: "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." + 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." Break-Fix: 8db14ca12569fe885694bd3d5ff84c2d973d3cb0 5bccda0ebc7c0331b81ac47d39e4b920b198b2cd
