Loading vulnerability…
A double-free vulnerability existed in the Linux kernel SMB client replay handling for query_info(). During a response-bearing attempt, the operation could return a replayable error and free its response buffer. If SMB2_query_info_init() then failed before the next send attempt, cleanup could retain stale response bookkeeping from the previous attempt, including the prior buffer type, and free the same response a second time. The flaw is caused by incorrect state management across retry attempts in the SMB client request path. The fix resets response bookkeeping before each attempt so stale response state cannot trigger a second free.
