Linux Kernel DMA Engine Tegra Memory Leak Vulnerability in Transfer Termination

A memory leak vulnerability has been addressed in the Linux kernel's DMA engine for Tegra. The issue arose in the 'terminate_all()' function, where the virtual descriptor (vdesc) was not properly managed during the termination of ongoing transfers. This oversight could lead to memory leaks. The vulnerability has been fixed by ensuring that the vdesc is added to the 'desc_terminated' list, allowing for proper cleanup later.

Impact

Exploitation of this vulnerability could lead to memory leaks, potentially causing increased memory usage and degradation of system performance over time.
