Linux Kernel LPC18XX DMAMUX Device Leak Vulnerability

A vulnerability in the Linux kernel's DMA engine driver for the LPC18XX DMAMUX has been addressed. The issue involved a device leak during route allocation, where a reference to the DMA mux platform device was not properly released. This could potentially lead to resource mismanagement, as holding onto the device reference does not prevent its driver data from being cleared, making the reference unnecessary.

Impact

The vulnerability could cause a device reference leak, leading to improper resource management.

Remediation

Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
