Triggering it requires local presence on the system (module autoload/device instantiation, or applying a DT overlay).\nAC:L - The out-of-bounds read is a deterministic consequence of the DT shape — any node whose `reg` is shorter than its interrupt parent's `#address-cells` hits it on every parse, with no race, timing window, or memory-layout condition to win. A party able to supply DT data arranges it trivially, and on an affected platform it fires unconditionally.\nPR:L - On a platform whose shipped device tree carries the `reg`/`#address-cells` mismatch — a real, observed configuration in the reporting bug — an unprivileged local user can drive the affected node through `device_add()`/`platform_get_irq()` by triggering module autoload or device instantiation, with no capability required. Full control over the DT blob would need root or firmware access, but that stronger requirement is not necessary to reach the faulty read.\nUI:N - Interrupt resolution happens automatically during device registration and driver probe; no victim action such as opening a file or mounting a filesystem is involved.\nS:U - The out-of-bounds read and its consequences are confined to kernel memory and kernel IRQ-routing state within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Up to ~60 bytes of adjacent slab memory beyond the `reg` allocation are read into `initial_match_array`, well past the \"few bytes\" threshold and unconstrained as to what neighbouring heap object is disclosed. The values then steer interrupt-map matching, so the resulting IRQ assignment observable in `/proc/interrupts` acts as an oracle on out-of-bounds heap contents.\nI:L - The out-of-bounds bytes are used directly as the match key for the interrupt-map walk, so uninitialized adjacent-heap data determines which interrupt parent and hwirq the device is bound to — a genuine but bounded corruption of kernel device configuration. There is no write primitive, so arbitrary modification or control-flow hijack is not achievable.\nA:H - With KASAN or arm64 MTE (`KASAN_HW_TAGS`, enabled on production Android) and `kasan.fault=panic`, the slab out-of-bounds read is an immediate kernel panic; for the base unflattened DT blob the read can also run past the final page and oops. Misrouted interrupts from a bogus match additionally leave the affected device non-functional." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
