Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists where the
ntb epf vec isr() function calls pci irq vector() within a hardirq context to determine the vector number. Because pci irq vector() subsequently calls msi get virq(), which requires a mutex, it can lead to scheduling while atomic errors.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
