Details

In the Linux kernel, the following vulnerability has been resolved:

mtd: rawnand: atmel: fix refcount issue in atmelnandcontroller_init

The reference counting issue happens in several error handling paths on a refcounted object "nc->dmac". In these paths, the function simply returns the error code, forgetting to balance the reference count of "nc->dmac", increased earlier by dmarequestchannel(), which may cause refcount leaks.

Fix it by decrementing the refcount of specific object in those error paths.
