08 May 2025 — In the Linux kernel, the following vulnerability has been resolved: io_uring: always do atomic put from iowq io_uring always switches requests to atomic refcounting for iowq execution before there is any parallilism by setting REQ_F_REFCOUNT, and the flag is not cleared until the request completes. That should be fine as long as the compiler doesn't make up a non existing value for the flags, however KCSAN still complains when the request owner changes oter flag bits: BUG: KCSAN: data-race in io_req_task_ca... • https://git.kernel.org/stable/c/2b188cc1bb857a9d4701ae59aa7768b5124e262e •

The issue occurs due to a time-of-check/time-of-use condition in hfsc_change_class() when working with certain child qdiscs like netem or codel. The vulnerability works as follows: 1. hfsc_change_class() checks if a class has packets (q.qlen != 0) 2.
