Title
of/irq: Prevent device address out-of-bounds read in interrupt map walk
Summary
In the Linux kernel, the following vulnerability has been resolved: of/irq: Prevent device address out-of-bounds read in interrupt map walk When of_irq_parse_raw() is invoked with a device address smaller than the interrupt parent node (from #address-cells property), KASAN detects the following out-of-bounds read when populating the initial match table (dyndbg="func of_irq_parse_* +p"): OF: of_irq_parse_one: dev=/soc@0/picasso/watchdog, index=0 OF: parent=/soc@0/pci@878000000000/gpio0@17,0, intsize=2 OF: intspec=4 OF: of_irq_parse_raw: ipar=/soc@0/pci@878000000000/gpio0@17,0, size=2 OF: -> addrsize=3 ================================================================== BUG: KASAN: slab-out-of-bounds in of_irq_parse_raw+0x2b8/0x8d0 Read of size 4 at addr ffffff81beca5608 by task bash/764 CPU: 1 PID: 764 Comm: bash Tainted: G O 6.1.67-484c613561-nokia_sm_arm64 #1 Hardware name: Unknown Unknown Product/Unknown Product, BIOS 2023.01-12.24.03-dirty 01/01/2023 Call trace: dump_backtrace+0xdc/0x130 show_stack+0x1c/0x30 dump_stack_lvl+0x6c/0x84 print_report+0x150/0x448 kasan_report+0x98/0x140 __asan_load4+0x78/0xa0 of_irq_parse_raw+0x2b8/0x8d0 of_irq_parse_one+0x24c/0x270 parse_interrupts+0xc0/0x120 of_fwnode_add_links+0x100/0x2d0 fw_devlink_parse_fwtree+0x64/0xc0 device_add+0xb38/0xc30 of_device_add+0x64/0x90 of_platform_device_create_pdata+0xd0/0x170 of_platform_bus_create+0x244/0x600 of_platform_notify+0x1b0/0x254 blocking_notifier_call_chain+0x9c/0xd0 __of_changeset_entry_notify+0x1b8/0x230 __of_changeset_apply_notify+0x54/0xe4 of_overlay_fdt_apply+0xc04/0xd94 ...

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 \u2014 any node whose `reg` is shorter than its interrupt parent\u0027s `#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 \u2014 a real, observed configuration in the reporting bug \u2014 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 \u2014 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."
