In the Linux kernel, the following vulnerability has been resolved: smb: client: fix query directory replay double-free A response-bearing attempt can return a replayable error and free its response buffer. If SMB2_query_directory_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.

A flaw was found in the Linux kernel's Server Message Block (SMB) client. This vulnerability, a double-free error, occurs when the client attempts to free the same memory buffer twice during a directory query operation. An attacker could potentially exploit this flaw to cause memory corruption, leading to a denial of service or, in some cases, arbitrary code execution.
