Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved. The issue is related to the access of the PCI config space via
pci ops::read and pci ops::write, which are low-level hardware accesses that can be performed with disabled interrupts even on PREEMPT RT. The vmd dev::cfg lock is accessed in the same context as the pci lock, which is a raw spinlock t. However, a spinlock t becomes a sleeping lock on PREEMPT RT and cannot be acquired with disabled interrupts. The vulnerability was reported as a bug where a sleeping function was called from an invalid context.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
