Background
The s390/gmap package is a component of the Linux Kernel, which is responsible for managing the General Purpose Address Mapping (GMAP) on IBM System z architectures. GMAP provides a mechanism for mapping virtual addresses to physical addresses. It is a critical part of the kernel's memory management subsystem and plays a crucial role in ensuring the proper functioning of the system.
Vulnerability Detail
The vulnerability identified in s390/gmap allows for voluntary scheduling during key setting. This means that an attacker could potentially exploit this vulnerability to execute arbitrary code or disrupt the normal operation of the system. By manipulating the scheduling mechanism during the key setting process, an attacker could gain unauthorized access or cause a denial-of-service (DoS) condition. The impact and attack plausibility of this vulnerability have not been proven yet.
