CVE-2026-99130 Oct 28, 2026 Source: Vendor
In the Linux kernel, the following vulnerability has been resolved:
io_uring/cancel: don't spin on local work the task can't run
io_uring_cancel_generic() refuses to sleep while any ring on the exiting
task's tctx has local work pending. It assumes the task is that ring's
submitter and that the next io_uring_try_cancel_requests() pass will run
the work. This does not hold for a ring that was still
IORING_SETUP_R_DISABLED when the task got its tctx node from
io_uring_create() or io_ringfd_regis
