- What exactly is meant by de-referencing a NULL pointer?
The C standard says that it is undefined behavior to dereference a null pointer This means that absolutely anything could happen: the program could crash, it could continue working silently, or it could erase your hard drive (although that's rather unlikely)
- Null Dereference - OWASP Foundation
A null-pointer dereference takes place when a pointer with a value of NULL is used as though it pointed to a valid memory area Null-pointer dereferences, while common, can generally be found and corrected in a simple way
- Understanding and Preventing NULL Pointer Dereference
A NULL pointer dereference, also known as a null dereference, occurs when a program attempts to access or manipulate memory using a pointer that has a value of NULL (a special value representing the absence of a valid memory address)
- Dereferencing Null Pointers: How to Avoid a Program Crash
A null pointer dereference occurs when a program ties to access the data stored at a memory location that is set to NULL, often resulting in an error or crash Null pointer dereferencing can happen due to a variety of reasons, such as race conditions and programming oversights
- How to Fix Dereferencing a NULL Pointer Error: A Comprehensive Guide
The 'Dereferencing a NULL Pointer' error is a common and frustrating issue in C and C++ programming This guide explains what causes this error, how to identify it, and provides practical solutions and prevention techniques with code examples, enhancing your debugging skills and code robustness
- CWE - CWE-476: NULL Pointer Dereference (4. 17)
Chain: a message having an unknown message type may cause a reference to uninitialized memory resulting in a null pointer dereference (CWE-476) or dangling pointer (CWE-825), possibly crashing the system or causing heap corruption
- Understanding Null Pointer Dereferences and How to Avoid Them
You can avoid null pointer dereferences by always initializing your pointers, checking if pointers are null before using them, using smart pointers in C++, adopting defensive programming techniques, and using static analysis tools to detect potential issues
- Null Pointer Dereferencing — MCSI Library
Null pointer dereferencing, often referred to as a null pointer dereference or simply a null dereference, is a programming error that occurs when a program attempts to access or dereference a memory address that contains a null value (a memory address with no valid data)
