In the Linux kernel, the following vulnerability has been resolved:
NFSD: fix leaked reference count of nfsd4_ssc_umount_item
The reference count of nfsd4_ssc_umount_item is not decremented on error conditions. This prevents the laundromat from unmounting the vfsmount of the source file.
This patch decrements the reference count of nfsd4_ssc_umount_item on error.
