(3) Event check_after_deref: Null-checking "thread->args" suggests that it may be null, but it has already been dereferenced on all paths leading to the check. 728 if (thread->args != NULL) { 729 stdi_free_ind_args(&thread->args); 730 } Resolve by changing the initialization to only set 'args', 'context', and 'prefix' if thread->args is not NULL. Each is initialized to NULL so the if prefix == NULL is still valid --- src/Virt_ComputerSystemIndication.c | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) diff --git a/src/Virt_ComputerSystemIndication.c b/src/Virt_ComputerSystemIndication.c index 1ae8193..04e4d89 100644 --- a/src/Virt_ComputerSystemIndication.c +++ b/src/Virt_ComputerSystemIndication.c @@ -600,9 +600,9 @@ static CMPI_THREAD_RETURN lifecycle_thread_native(void *params) { CU_DEBUG("Entering libvirtc-cim native CSI thread."); csi_thread_data_t *thread = (csi_thread_data_t *) params; - struct ind_args *args = thread->args; - CMPIContext *context = args->context; - char *prefix = class_prefix_name(args->classname); + struct ind_args *args = NULL; + CMPIContext *context = NULL; + char *prefix = NULL; virConnectPtr conn; CMPIStatus s; int retry_time = FAIL_WAIT_TIME; @@ -614,6 +614,11 @@ static CMPI_THREAD_RETURN lifecycle_thread_native(void *params) virDomainPtr *tmp_list = NULL; int CBAttached = 0; + if (thread->args != NULL) { + args = thread->args; + context = args->context; + prefix = class_prefix_name(args->classname); + } if (prefix == NULL) { goto init_out; } -- 1.8.1.4
