Background
The riscv Kernel is a component of the Linux operating system that supports the RISC-V architecture. It provides the necessary functionality for the RISC-V processors to operate efficiently. The irqsoff latency tracer is a feature in the kernel that helps analyze the latency of interrupt handlers. However, a vulnerability has been discovered in this tracer, which can lead to oops (out-of-memory) errors. This vulnerability can potentially impact the stability and performance of systems running on the riscv Kernel.
Vulnerability Detail
The vulnerability in the riscv Kernel is caused by a flaw in the irqsoff latency tracer. When this tracer is enabled, it can trigger oops errors, resulting in system crashes or instability. An attacker could potentially exploit this vulnerability to disrupt the normal operation of a system or even execute arbitrary code. The vulnerability was introduced in version v5.9 of the Linux Kernel and has been fixed in version v5.10.103 by commit 9e2dbc31e367d08ee299a0d8aeb498cb2e12a1c3.
