Background
The Kernel is a critical component of the Linux operating system that provides core functionality and interfaces with hardware devices. It manages the communication between software and hardware, including handling input/output operations. The scsi (Small Computer System Interface) subsystem in the Kernel is responsible for managing SCSI devices, such as hard drives and tape drives. The sysfs (system file system) is a virtual file system that provides a way to interact with the Kernel and access device information. However, a vulnerability has been discovered in the scsi core sysfs implementation that can lead to a hang when the device state is set via sysfs.
Vulnerability Detail
The vulnerability in the scsi core sysfs implementation allows an attacker to cause a hang in the system by setting the device state via sysfs. This can be exploited by an attacker with local access to the system to disrupt normal operation and potentially cause a denial-of-service (DoS) condition. The vulnerability was introduced in Linux Kernel version v5.10.61 and has been fixed in version v5.10.82. The specific commit that addresses this issue is a792e0128d232251edb5fdf42fb0f9fbb0b44a73. It is important to note that the impact and attack plausibility of this vulnerability have not yet been proven.
