答:Dereferencing a null pointer in C++ leads to undefined behavior, which means that the program can behave inunpredictableways or crash. When you dereference a null pointer, you are trying to access the memory location pointed to by the pointer, but the pointer does not point to any valid ...
NULL pointer dereferenced expand all in page Description This defect occurs when you use a pointer with a value of NULL as if it points to a valid memory location. If you dereference the zero address, such as 0x00, Polyspace® considers the null address as equivalent to NULL and raises ...
Because a null pointer does not point to a meaningful object, an attempt to dereference (ie. access the data stored at that memory location) a null pointer usually (but not always) causes a run-time error or immediate program crash. 被CWE(Common Weakness Enumeration)收录的一种程序缺陷类型。

作为Comate,我很乐意帮助你理解并解决“attempted to dereference null pointer”这一常见问题。下面我将按照你的提示逐一解答: 1. 解释什么是空指针和解引用空指针的含义 空指针:在编程中,空指针是指没有指向任何有效内存地址的指针。在大多数编程语言中,空指针通常被初始化为null(在一些语言中可能是nil、None等)...
dereference of an explicit null value Dereferencing an explicit null value refers to accessing the memory location pointed to by a null pointer. In most programming languages, a null pointer represents a value that does not point to any memory location. When attempting to dereference a null ...
Unknown Description A null pointer dereference flaw was found in Libtiff viatif_dirinfo.c. This issue may allow an attacker to trigger memory allocation failures through certain means, such as restricting the heap space size or injecting faults, causing a segmentation fault. This can cause an app...
