Title
ASoC: Intel: soc-acpi-intel-lnl-match: add missing empty item
Summary
In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: soc-acpi-intel-lnl-match: add missing empty item There is no links_num in struct snd_soc_acpi_mach {}, and we test !link->num_adr as a condition to end the loop in hda_sdw_machine_select(). So an empty item in struct snd_soc_acpi_link_adr array is required.

Re-triggering it requires local driver bind/rebind or a reboot of the affected Lunar Lake platform.\nAC:L - On an affected platform (Intel LNL with a cs42l43 on SoundWire link 0) the unterminated array is walked deterministically on every probe, with no race, timing window, or memory-layout grooming required. There are no conditions the attacker must win or wait for.\nPR:L - No authentication or capability check gates the code \u2014 it runs during device probe \u2014 but deliberately causing the probe to re-execute (module load or `/sys/bus/pci/drivers/.../bind`) requires local system access. No remote credentials or user-namespace escalation are involved.\nUI:N - The vulnerable loop executes automatically during driver probe at boot; no victim must open a file, mount a filesystem, or take any action.\nS:U - Both the defective data and the faulting reads are within the kernel\u0027s own security authority; nothing crosses a VM, IOMMU, or sandbox boundary.\nC:H - This is an out-of-bounds read that is not confined to a few bytes: `hda_sdw_machine_select` reads up to three 16-byte structs past the array, and the OOB-derived `adr_d`/`name_prefix` pointers are then dereferenced in `snd_soc_acpi_sdw_link_slaves_found()` and `parse_sdw_endpoints()`, allowing kernel memory at an uncontrolled address to be read. In the `sof_sdw` path the walk is entirely unbounded and OOB `name_prefix` strings can surface in DAI-link/component names exposed to userspace via /proc/asound and sysfs.\nI:L - There is no out-of-bounds write or arbitrary-write primitive, but the kernel selects the audio machine driver, topology firmware file, and constructs DAI-link/endpoint structures from data read past the end of the array, so kernel state and device configuration are derived from invalid memory.\nA:H - The OOB entry supplies both a `num_adr` count and an `adr_d` pointer that are dereferenced without validation, so a neighbouring `.rodata` object that is not a valid `snd_soc_acpi_link_adr` produces a wild-pointer read and a kernel oops at probe time; the unbounded walk in `sof_sdw.c` compounds this. On the observed layout the machine fails to match, causing complete loss of audio functionality on affected devices."

Re-triggering it requires local driver bind/rebind or a reboot of the affected Lunar Lake platform.\nAC:L - On an affected platform (Intel LNL with a cs42l43 on SoundWire link 0) the unterminated array is walked deterministically on every probe, with no race, timing window, or memory-layout grooming required. There are no conditions the attacker must win or wait for.\nPR:L - No authentication or capability check gates the code \u2014 it runs during device probe \u2014 but deliberately causing the probe to re-execute (module load or `/sys/bus/pci/drivers/.../bind`) requires local system access. No remote credentials or user-namespace escalation are involved.\nUI:N - The vulnerable loop executes automatically during driver probe at boot; no victim must open a file, mount a filesystem, or take any action.\nS:U - Both the defective data and the faulting reads are within the kernel\u0027s own security authority; nothing crosses a VM, IOMMU, or sandbox boundary.\nC:H - This is an out-of-bounds read that is not confined to a few bytes: `hda_sdw_machine_select` reads up to three 16-byte structs past the array, and the OOB-derived `adr_d`/`name_prefix` pointers are then dereferenced in `snd_soc_acpi_sdw_link_slaves_found()` and `parse_sdw_endpoints()`, allowing kernel memory at an uncontrolled address to be read. In the `sof_sdw` path the walk is entirely unbounded and OOB `name_prefix` strings can surface in DAI-link/component names exposed to userspace via /proc/asound and sysfs.\nI:L - There is no out-of-bounds write or arbitrary-write primitive, but the kernel selects the audio machine driver, topology firmware file, and constructs DAI-link/endpoint structures from data read past the end of the array, so kernel state and device configuration are derived from invalid memory.\nA:H - The OOB entry supplies both a `num_adr` count and an `adr_d` pointer that are dereferenced without validation, so a neighbouring `.rodata` object that is not a valid `snd_soc_acpi_link_adr` produces a wild-pointer read and a kernel oops at probe time; the unbounded walk in `sof_sdw.c` compounds this. On the observed layout the machine fails to match, causing complete loss of audio functionality on affected devices."

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
