Background
The scsi: qla2xxx package is a component of the Linux Kernel. It provides support for QLogic Fibre Channel Host Bus Adapters (HBAs). These HBAs are used for connecting servers to storage devices in enterprise environments. The qla2xxx driver is responsible for managing the communication between the host system and the Fibre Channel network. It handles tasks such as initializing the HBA, establishing connections, and transferring data.
However, a vulnerability has been discovered in the qla2xxx driver that allows for improper scheduling while in an atomic context. This can lead to potential race conditions and other concurrency issues, which may result in system instability or crashes. An attacker with local access to the system could potentially exploit this vulnerability to gain elevated privileges or disrupt the normal operation of the system.
Vulnerability Detail
The vulnerability in the qla2xxx driver arises from improper scheduling while in an atomic context. Atomic operations are used to ensure that certain critical sections of code are executed without interruption. However, if scheduling is allowed within an atomic context, it can lead to race conditions and other concurrency issues.
An attacker with local access to the system could potentially exploit this vulnerability by carefully timing their actions to trigger a race condition. This could allow them to gain elevated privileges or disrupt the normal operation of the system.
The vulnerability has been assigned the ID GSD-2022-1001123 and is fixed in Linux Kernel version v5.17.2 by commit 78612f2fe8e26637476d756a44f0f05cca0d97de.
