Background
The Kernel package is a crucial component of the Linux operating system, responsible for managing system resources and providing an interface between hardware and software. It includes various subsystems, such as interrupt handling, which allows the system to respond to hardware events. The powerpc/64s/interrupt module specifically handles interrupts on 64-bit PowerPC systems. However, a vulnerability has been discovered in this module that could lead to a race condition when exiting interrupts in the presence of security mitigation switches.
Vulnerability Detail
The vulnerability in the powerpc/64s/interrupt module arises from a race condition during interrupt exit when security mitigation switches are enabled. This race condition could potentially be exploited by an attacker to gain unauthorized access or disrupt the system. The vulnerability was introduced in version v5.14 of the Linux Kernel and has been fixed in version v6.1.12. The impact and attack plausibility of this vulnerability have not been proven yet.
