Problems solved by technology

[0005] In view of this, the embodiments of the present invention provide a method, device, and electronic device for releasing a mutex, which can improve the security protection efficiency of the operating system and solve the problem of mutual exclusion on the process in the existing method for obtaining the process path. The lock phenomenon, the problem of low security protection efficiency of the operating system caused by calling the enumeration process virtual memory kernel function to obtain process path information is likely to cause the operating system to crash, making it impossible to check and kill the process

Abstract

An embodiment of the invention discloses a mutually-exclusive lock release method and device and electronic equipment and relates to information safety technology. The mutually-exclusive lock release method and device is conducive to improving safety protection efficiency of an operation system. The method includes: acquiring process resource lock information in a process environment block, and acquiring a locking field in the process resource lock information; judging whether the locking field in the process resource information is in a locked state or not; if yes, updating the locking field into a unlocked state according to a pointer of the process resource lock information.

Description

technical field [0001] The invention relates to information security technology, in particular to a method, device and electronic equipment for releasing a mutual exclusion lock. Background technique [0002] With the gradual disclosure of the technical details of the kernel layer of the Windows system, more and more malicious applications (APP, Application) such as Trojan horse viruses, for their own survival and illegal interests, begin to use kernel layer drivers to protect their own process files. The process corresponding to the process file of the malicious application program protected by the kernel layer driver can end (kill) the security protection process in the Windows system, for example, the process of antivirus software or firewall software, so that the process of the malicious application program can The intent of the application provider is to maliciously attack the user's process or system process, which may cause the computer to run unstable, and may even c...
