Null Pointer Dereference
A null pointer dereference occurs when a program attempts to access memory through a pointer that has been set to NULL (address 0x0).
How It Works
A null pointer dereference occurs when a program attempts to access memory through a pointer that has been set to NULL (address 0x0). In normal operation, pointers should reference valid memory locations before use. When a pointer is NULL—either uninitialized, explicitly set to NULL, or returned as NULL from a failed allocation—and the program tries to read from, write to, or execute code at that address, the operating system intervenes. On modern systems, accessing address zero triggers a segmentation fault that immediately terminates the process.
Attackers exploit this by manipulating program logic to force null pointer conditions. Common techniques include triggering allocation failures in low-memory conditions, providing malformed input that bypasses initialization checks, or exploiting race conditions where a pointer is checked for NULL but becomes NULL before use. The attacker identifies code paths where null checks are missing or inadequate, then crafts inputs to reach those vulnerable states.
On legacy systems without memory protection, attackers could map their own code at address zero, converting a crash into arbitrary code execution. Modern operating systems prevent this through mmap_min_addr restrictions that prohibit mapping memory below a threshold (typically 64KB). This mitigation has largely relegated null pointer dereferences to denial-of-service attacks rather than remote code execution vectors.
Impact
- Service disruption: Immediate process crash, taking down the vulnerable application or daemon
- Availability attacks: Repeated crashes forcing system restarts or service downtime
- Limited code execution: On unpatched legacy systems (pre-2009 Linux kernels, older embedded devices) where address zero mapping is possible
- Privilege escalation: In kernel-mode drivers where null dereferences can be exploited to execute attacker code with system privileges
Real-World Examples
The Linux kernel suffered from CVE-2009-2908, where null pointer dereferences in various subsystems could be exploited on systems allowing mmap at address zero. Attackers could map malicious code at NULL and trigger kernel null dereferences to achieve privilege escalation. This prompted the introduction of mmap_min_addr protections.
Microsoft Windows drivers have been frequent targets, including CVE-2020-17087 in the Windows kernel cryptography driver. Attackers triggered null pointer dereferences in kernel mode, which on older Windows versions could be exploited for local privilege escalation by controlling the null page.
Web browsers have experienced denial-of-service through null dereferences when parsing malformed content. Firefox CVE-2019-11707 involved a null pointer dereference in the IonMonkey JIT compiler, allowing attackers to crash the browser with specially crafted JavaScript, though not achieve code execution due to modern protections.
Mitigation
- Explicit null checks: Validate all pointers before dereferencing, especially after allocation or function calls that may return NULL
- Static analysis tools: Deploy analyzers like Coverity, Clang Static Analyzer, or PVS-Studio to detect missing null checks during development
- Address space layout: Enable
mmap_min_addrkernel protection (standard on modern Linux, typically 65536 bytes) - Fuzzing: Use AFL, libFuzzer, or similar tools to stress-test error handling paths and allocation failures
- Safe coding practices: Initialize pointers to NULL, use smart pointers in C++, adopt languages with built-in null safety
- Runtime bounds checking: Enable AddressSanitizer during testing to catch null dereferences immediately
