“Null pointer dereference”(空指针引用)是指在程序中尝试访问或操作一个值为null的对象引用时发生的错误。这种操作会导致程序抛出NullPointerException,通常意味着代码中存在逻辑错误,因为任何对null引用的操作都是非法的。 2. 分析为何在Android开发中会出现“null pointer dereference” 在Android开发中,出现“null po...
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...
int &x = *(int *)nullptr; // Error: null reference Solution Use a pointer instead. int *x = nullptr; // Correct Member access through a null pointer in C++ The following code makes a member call on an object with a null address. The compiler may remove the null ...
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 ...
