CVE-2022-50234

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> io_uring/af_unix: defer registered files gc to io_uring release<br /> <br /> Instead of putting io_uring&amp;#39;s registered files in unix_gc() we want it<br /> to be done by io_uring itself. The trick here is to consider io_uring<br /> registered files for cycle detection but not actually putting them down.<br /> Because io_uring can&amp;#39;t register other ring instances, this will remove<br /> all refs to the ring file triggering the -&gt;release path and clean up<br /> with io_ring_ctx_free().<br /> <br /> [axboe: add kerneldoc comment to skb, fold in skb leak fix]
