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

Description The issue is related to a deadlock scenario in the Linux kernel's dma-debug component. The dma entry alloc check leak() function calls into printk and grabs the port->lock under the free entries lock spin lock, creating a reverse locking dependency chain. This can lead to a deadlock when the qcom geni IRQ handler calls into dma-debug code and grabs the free entries lock under the port->lock. The vulnerability can cause a denial of service.

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