There is no network, adjacent-network, or removable-device path into this hwmon driver.\nAC:L - On an affected target (an Intel package with more than 128 cores, e.g. 144-core Sierra Forest sockets) the out-of-bounds write is fully deterministic \u2014 it fires on every boot and on every CPU-online cycle once the IDA index passes 127, with no race, no grooming, and no per-attempt uncertainty. Target-configuration/hardware dependence is not AC:H under CVSS 3.1.\nPR:L - The driver performs no capability or credential check anywhere on the `coretemp_cpu_online()` \u2192 `coretemp_add_core()` \u2192 `create_core_data()` path; the corruption occurs during ordinary CPU bring-up with no privilege held at all, and the runtime re-trigger is CPU hotplug. Scoring the more severe of the arguable options (boot/module-load-reachable by a low-privileged local presence) rather than requiring full root.\nUI:N - CPU onlining and coretemp initialization happen automatically as part of normal system startup and hotplug handling. No victim action of any kind is required.\nS:U - The out-of-bounds write corrupts fields inside the kernel\u0027s own `struct platform_data` allocation and the follow-on damage stays in kernel slab memory on the same host. No VM, IOMMU, or sandbox security boundary is crossed.\nC:H - Indices 135\u2013138 overwrite `ida.xa.xa_head` two bytes at a time, leaving a near-valid kernel pointer that the next `ida_alloc_range()` dereferences via `xas_find_marked()`/`find_next_zero_bit()`, reading arbitrary kernel slab memory as an `xa_node`/`ida_bitmap`. The corrupted `pd-\u003ecpumask` also redirects `rdmsr_on_cpu()` targets for the sysfs temperature readers.\nI:H - This is an out-of-bounds write that clobbers a live kernel pointer, the xarray spinlock and flags, and the CPU mask inside `struct platform_data`. The resulting type confusion lets `__set_bit()` in `ida_alloc_range()` write into misinterpreted kernel memory, and corrupted `core_data[]`/cpumask state can drive bogus `kfree()` and stale-sysfs teardown in `coretemp_remove_core()`.\nA:H - Once `xa_head` is corrupted, the next IDA operation walks a garbage or non-canonical pointer, producing an immediate oops or GP fault; corrupting the xarray spinlock can also wedge the hotplug path. Any of these is a kernel crash or hang."

There is no network, adjacent-network, or removable-device path into this hwmon driver.\\nAC:L - On an affected target (an Intel package with more than 128 cores, e.g. 144-core Sierra Forest sockets) the out-of-bounds write is fully deterministic \\u2014 it fires on every boot and on every CPU-online cycle once the IDA index passes 127, with no race, no grooming, and no per-attempt uncertainty. Target-configuration/hardware dependence is not AC:H under CVSS 3.1.\\nPR:L - The driver performs no capability or credential check anywhere on the `coretemp_cpu_online()` \\u2192 `coretemp_add_core()` \\u2192 `create_core_data()` path; the corruption occurs during ordinary CPU bring-up with no privilege held at all, and the runtime re-trigger is CPU hotplug. Scoring the more severe of the arguable options (boot/module-load-reachable by a low-privileged local presence) rather than requiring full root.\\nUI:N - CPU onlining and coretemp initialization happen automatically as part of normal system startup and hotplug handling. No victim action of any kind is required.\\nS:U - The out-of-bounds write corrupts fields inside the kernel\u0027s own `struct platform_data` allocation and the follow-on damage stays in kernel slab memory on the same host. No VM, IOMMU, or sandbox security boundary is crossed.\\nC:H - Indices 135\\u2013138 overwrite `ida.xa.xa_head` two bytes at a time, leaving a near-valid kernel pointer that the next `ida_alloc_range()` dereferences via `xas_find_marked()`/`find_next_zero_bit()`, reading arbitrary kernel slab memory as an `xa_node`/`ida_bitmap`. The corrupted `pd-\u003ecpumask` also redirects `rdmsr_on_cpu()` targets for the sysfs temperature readers.\\nI:H - This is an out-of-bounds write that clobbers a live kernel pointer, the xarray spinlock and flags, and the CPU mask inside `struct platform_data`. The resulting type confusion lets `__set_bit()` in `ida_alloc_range()` write into misinterpreted kernel memory, and corrupted `core_data[]`/cpumask state can drive bogus `kfree()` and stale-sysfs teardown in `coretemp_remove_core()`.\\nA:H - Once `xa_head` is corrupted, the next IDA operation walks a garbage or non-canonical pointer, producing an immediate oops or GP fault; corrupting the xarray spinlock can also wedge the hotplug path.
