CVE-2022-49893

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> cxl/region: Fix cxl_region leak, cleanup targets at region delete<br /> <br /> When a region is deleted any targets that have been previously assigned<br /> to that region hold references to it. Trigger those references to<br /> drop by detaching all targets at unregister_region() time.<br /> <br /> Otherwise that region object will leak as userspace has lost the ability<br /> to detach targets once region sysfs is torn down.
