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

Description A resource leak exists in the fsl pamu probe() function within the iommu/fsl pamu module of the Linux kernel. Specifically, the function returns prematurely when create csd() fails, resulting in unreleased interrupt requests (irq) and memory resources. The issue is addressed by adding an error jump to ensure proper resource cleanup if create csd() encounters an error.

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