  "details": "In the Linux kernel, the following vulnerability has been resolved:  bpf: Require a BPF cpumask for bpf_cpumask_populate()  bpf_cpumask_populate() writes to its destination with bitmap_copy(), but the destination is typed as struct cpumask *. That allows the verifier to accept borrowed cpumask pointers returned by read-only kfuncs, such as scx_bpf_get_online_cpumask(), as a writable destination.  Make the destination a struct bpf_cpumask * so populate follows the same ownership rule as the other mutating cpumask kfuncs. Query kfuncs continue to accept const struct cpumask * inputs.",
