不過工作 (和 cgroup) 本機儲存已移至可在 raw_spin_lock 之後使用的 bpf 記憶體配置器。展開用於 sk 儲存。針對 sk (和 inode) 儲存其尚未移至 bpf 記憶體配置器。無論是否使用 raw_spin_lockkzalloc(GFP_ATOMIC) 在追踪內容中理論上可能是不安全的。但是本機儲存協助程式需要驗證器接受的 sk 指標 (PTR_TO_BTF_ID)假設會發生這種情況 (是指在 kzalloc 不安全的內容中執行 bpf prog同時也能容納驗證器接受的 sk 指標)。此修補程式可避免 kzalloc 在 raw_spin_lock 之後使 splat 無訊息。在 raw_spin_lock 之前有一個現有的 kzalloc。此時很可能需要 kzalloc因為之前剛剛完成查閱。因此此修補程式一律先執行 kzalloc再執行 acq ---truncated--- (CVE-2023-53857)
