What it is

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

smb: client: close handle after create-context parsing failure

SMB2_open() accounts a successful CREATE response as a remote open before

parsing its create contexts. If smb2_parse_contexts() rejects malformed

context data, SMB2_open() returns without closing the handle, leaving the

server-side handle open and num_remote_opens elevated.

Close the handle after a post-CREATE context parsing failure so the error

path releases the remote resource and balances the open count.
