  "details": "In the Linux kernel, the following vulnerability has been resolved:  SUNRPC: auth_gss: fix memory leaks in XDR decoding error paths  The gssx_dec_ctx(), gssx_dec_status(), and gssx_dec_name() functions allocate memory via gssx_dec_buffer(), which calls kmemdup(). When a subsequent decode operation fails, these functions return immediately without freeing previously allocated buffers, causing memory leaks.  The leak in gssx_dec_ctx() is particularly relevant because the caller (gssp_accept_sec_context_upcall) initializes several buffer length fields to non-zero values, resulting in memory allocation:      struct gssx_ctx rctxh = {         .exported_context_token.len = GSSX_max_output_handle_sz,         .mech.len = GSS_OID_MAX_LEN,         .src_name.display_name.len = GSSX_max_princ_sz,         .targ_name.display_name.len = GSSX_max_princ_sz     };  If, for example, gssx_dec_name() succeeds for src_name but fails for targ_name, the memory allocated for exported_context_token, mech, and src_name.display_name remains unreferenced and cannot be reclaimed.  Add error handling with goto-based cleanup to free any previously allocated buffers before returning an error.",
