In the Linux kernel, the following vulnerability has been resolved:  smb: client: fix double-free in SMB2close() replay  A response-bearing attempt can return a replayable error and free its response buffer. If SMB2close_init() fails before the next send, cleanup retains the previous buffer type and frees that response again.  Reset response bookkeeping before each attempt to prevent the stale free.
