Description
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.
Affected configurations
• linux linux kernel (>= 5.14 < 5.15.154)
• linux linux kernel (>= 5.16 < 6.1.16)
• linux linux kernel (>= 6.2 < 6.2.3)
