Descriptions
In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: atmel: fix refcount issue in atmel_nand_controller_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 dma_request_channel(), which may
cause refcount leaks. Fix it by decrementing the refcount of specific object in those error
paths.
The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security bugfixes. The following security bugs were fixed.
