Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved, specifically in the irqchip/riscv-aplic component. The issue occurs when the APLIC driver is probed before the IMSIC driver, resulting in a missing parent MSI domain. This causes a NULL pointer dereference in the msi create device irq domain() function. To avoid this, the probe is deferred until the parent MSI domain is available, and dev err probe() is used to prevent error messages when returning -EPROBE DEFER.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
