CVE-2025-38012

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> sched_ext: bpf_iter_scx_dsq_new() should always initialize iterator<br /> <br /> BPF programs may call next() and destroy() on BPF iterators even after new()<br /> returns an error value (e.g. bpf_for_each() macro ignores error returns from<br /> new()). bpf_iter_scx_dsq_new() could leave the iterator in an uninitialized<br /> state after an error return causing bpf_iter_scx_dsq_next() to dereference<br /> garbage data. Make bpf_iter_scx_dsq_new() always clear $kit-&gt;dsq so that<br /> next() and destroy() become noops.
