Background
The Kernel package is a critical component of the Linux operating system that provides core functionality and manages system resources. It includes various subsystems, such as the irqchip, which handles interrupt requests. The irqchip/gic-v3 module specifically deals with the Generic Interrupt Controller (GIC) version 3. This vulnerability in irqchip/gic-v3 involves enabling interrupts when handling spurious interrupts, which can lead to potential security risks.
Vulnerability Detail
The vulnerability in irqchip/gic-v3 arises from the incorrect enabling of interrupts during the handling of spurious interrupts. Spurious interrupts are interrupts that are mistakenly triggered by the system. By enabling interrupts in this scenario, an attacker could potentially exploit the system and gain unauthorized access or disrupt its normal operation. The impact and attack plausibility of this vulnerability have not been proven yet. It is important to note that this vulnerability has been fixed in Linux Kernel version v5.10.36.
