Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
smb: client: fix query_info() replay double-free<br />
<br />
A response-bearing attempt can return a replayable error and free its<br />
response buffer. If SMB2_query_info_init() fails before the next send,<br />
cleanup retains the previous buffer type and frees that response again.<br />
<br />
Reset response bookkeeping before each attempt to prevent the stale free.
