Technical Problem
[0002]非法内存访问通常与内存访问越界、野指针、内存泄漏和异步执行有关，其可以导致程序崩溃或数据损坏，还可能被恶意利用引发安全漏洞，造成严重后果
Benefits of technology
[0034]可见，本申请实施例的方法不需要以模式匹配和规则库为基础对目标程序片段的运行结果进行检测，而是对内存块中的保护区内的数据进行异常检测，并在保护区内的数据异常时，自动确定非法内存访问的位置信息，为问题修复提供详细依据，因此，本申请实施例的方法不仅不需要开发人员耗费时间调试和排查非法内存访问的发生位置，还不容易产生误报或漏报，可以覆盖到复杂的内存操作场景。

Abstract
The application provides a memory management method and a computer device. The method comprises the following steps: in response to a target program segment execution end event, obtaining memory protection area information in a physical memory; if it is detected that the memory protection area information is abnormal, obtaining execution context information corresponding to the target program segment; and based on the execution context information corresponding to the target program segment, determining position information of illegal memory access. The method can improve the positioning accuracy and universality of illegal memory access, reduce performance overhead, and ensure system stability and security.
