In the Linux kernel, the following vulnerability has been resolved:
iouring: fix incorrect iokiocb reference in iolinkskb
In iolinkskb function, there is a bug where prevnotif is incorrectly assigned using 'nd' instead of 'prevnd'. This causes the context validation check to compare the current notification with itself instead of comparing it with the previous notification.
Fix by using the correct prevnd parameter when obtaining prevnotif.
