The "sawtooth" pattern of memory utilization: the sudden drop in used memory is a candidate symptom for a memory leak. If the memory leak is in the kernel, the operating system itself will likely fail. Computers without sophisticated memory management, such as embedded systems, may also completely fail from a persistent memory leak.
Memory leak – when memory usage is not tracked or is tracked incorrectly Stack exhaustion – occurs when a program runs out of stack space, typically because of too deep recursion . A guard page typically halts the program, preventing memory corruption, but functions with large stack frames may bypass the page.
Resource leak. In computer science, a resource leak is a particular type of resource consumption by a computer program where the program does not release resources it has acquired. This condition is normally the result of a bug in a program. Typical resource leaks include memory leak and handle leak, particularly file handle leaks, though ...
Memory corruption occurs in a computer program when the contents of a memory location are modified due to programmatic behavior that exceeds the intention of the original programmer or program/language constructs; this is termed as violation of memory safety. The most likely causes of memory corruption are programming errors (software bugs).
Dangling pointer. Dangling pointers and wild pointers in computer programming are pointers that do not point to a valid object of the appropriate type. These are special cases of memory safety violations. More generally, dangling references and wild references are references that do not resolve to a valid destination.
In computer programming, the lapsed listener problem is a common source of memory leaks for object-oriented programming languages, among the most common ones for garbage collected languages. [1] It originates in the observer pattern, where observers (or listeners) register with a subject (or publisher) to receive events. In basic implementation ...
Improper management of memory is a common cause of bugs and security vulnerabilities, including the following types: A memory leak occurs when a program requests memory from the operating system and never returns the memory when it is done with it. A program with this bug will gradually require more and more memory until the program fails as ...
Resource exhaustion attacks generally exploit a software bug or design deficiency. In software with manual memory management (most commonly written in C or C++), memory leaks are a very common bug exploited for resource exhaustion. Even if a garbage collected programming language is used, resource exhaustion attacks are possible if the program ...
