      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsched_ext: Don't run ops.dequeue() with a DSQ lock held\n\nops.dequeue() is invoked with the source user DSQ's lock still held on\nthe consume and move paths (scx_consume_dispatch_q(),\nmove_task_between_dsqs()). A BPF scheduler which locks the source user\nDSQ from ops.dequeue() - e.g. by iterating it with bpf_iter_scx_dsq -\nself-deadlocks.\n\nops.dequeue() can only call the \"any\" kfuncs and none of them can lock a\nbuiltin DSQ, so the global and bypass paths can't deadlock; however,\nall DSQ locks share one lockdep class, so iterating any user DSQ from\nops.dequeue() on those paths trips the recursion check.\n\nMove the invocation after the DSQ unlock on all three paths.\nSCX_TASK_IN_CUSTODY is cleared under the lock serializing the transfer\nso that the callback is invoked exactly once.",
