Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> io_uring: check if we need to reschedule during overflow flush<br /> <br /> In terms of normal application usage, this list will always be empty.<br /> And if an application does overflow a bit, it&amp;#39;ll have a few entries.<br /> However, nothing obviously prevents syzbot from running a test case<br /> that generates a ton of overflow entries, and then flushing them can<br /> take quite a while.<br /> <br /> Check for needing to reschedule while flushing, and drop our locks and<br /> do so if necessary. There&amp;#39;s no state to maintain here as overflows<br /> always prune from head-of-list, hence it&amp;#39;s fine to drop and reacquire<br /> the locks at the end of the loop.
