The leak runs only when int3400_thermal_probe() fails after evaluate_odvp() but before the old free_sysfs label (thermal_tripless_zone_device_register(), sysfs_create_group() for uuids/imok, or device_create_bin_file()), or when evaluate_odvp() itself fails after allocating attrs; those are -ENOMEM/kernfs errors the attacker cannot force.\nPR:L - evaluate_odvp() creates each odvpN with mode 0444 on priv->pdev->dev.kobj; after probe kfree(priv) via free_art_trt without cleanup_odvp(), an unprivileged local user can open those leftover files and run odvp_show() with no CAP_SYS_ADMIN.\nUI:N - The attacker reads the leftover odvpN sysfs attributes themselves; no other user must mount media, bind int3400_thermal, or confirm a prompt.\nS:U - odvp_show() dereferences the probe-freed int3400_thermal_priv in the host kernel; this is not a VM, IOMMU, or sandbox escape.\nC:H - odvp_show() evaluates odvp_attr->priv->odvp[odvp_attr->odvp] after int3400_thermal_probe() kfree(priv) on free_art_trt, a slab UAF of int3400_thermal_priv that discloses kernel memory once that object is reclaimed.\nI:H -
