There is no remote or adjacent-network data path into `ocfs2_local_read_info()`.\nAC:L - The attacker authors the on-disk image and therefore controls both the failure trigger (unvalidated `dqi_chunks`/quota-block ECC guaranteeing an error after `ocfs2_global_read_info()` succeeds) and `dqi_syncms`, which sets the exact delay before the freed timer fires \u2014 giving a deterministic, repeatable free-then-spray-then-fire window. No condition outside the attacker's influence is required.\nPR:L - In the realistic worst case a low-privileged local user supplies the crafted image on removable media or via a delegated/`user` fstab mount and a privileged automounter (udisks2/systemd) performs the mount, so the attacker themself holds only unprivileged credentials. Per the uncertainty rule the lower privilege tier is taken over requiring real CAP_SYS_ADMIN.\nUI:N - On desktop, kiosk and shared-workstation deployments the mount is performed automatically by the automount daemon on media insertion \u2014 an action the attacker performs \u2014 so no separate victim interaction is needed.\nS:U - The freed object, the timer wheel and the work handler all live within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a slab use-after-free: the attacker can reallocate the freed `ocfs2_mem_dqinfo` and have `qsync_work_fn()` dereference an attacker-chosen `dqi_gqinode`/`i_sb`, and `dquot_scan_active()` then walks structures at attacker-influenced addresses, yielding an arbitrary-read primitive.\nI:H - `expire_timers()` reads `timer->function` from the freed object and calls it while `detach_timer()` writes back into it, so a successful heap spray gives a controlled indirect call and write primitive \u2014 full control-flow hijack, not merely state corruption.\nA:H - Even unexploited the dangling timer causes a wild function-pointer call or NULL/garbage dereference in softirq context, producing a
