In the Linux kernel, the following vulnerability has been resolved:

smb: client: fix oops due to uninitialised var in smb2 unlink()

If SMB2 open init() or SMB2 close init() fails (e.g. reconnect), the iovs set @rqst will be left uninitialised, hence calling SMB2 open free(), SMB2 close free() or smb2 set related() on them will oops.

Fix this by initialising @close iov and @open iov before setting them in @rqst.
