Description

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

Affected configurations

• linux linux kernel (>= 6.12 < 6.12.30) • linux linux kernel (>= 6.13 < 6.14.8) • linux linux kernel 6.15
