CVE-2024-36955: ALSA: hda: intel-sdw-acpi: fix usage of device_get_named_child_node()

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.24% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 722d33c442e66e4aabd3e778958d696ff3a2777e, 7db626d2730d3d80fd31638169054b1e507f07bf, 7ef6ecf98ce309b1f4e5a25cddd5965d01feea07.

Low priority for now. Upgrade to Linux Linux 722d33c442e66e4aabd3e778958d696ff3a2777e, 7db626d2730d3d80fd31638169054b1e507f07bf, 7ef6ecf98ce309b1f4e5a25cddd5965d01feea07 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: intel-sdw-acpi: fix usage of device_get_named_child_node() The documentation for device_get_named_child_node() mentions this important point: " The caller is responsible for calling fwnode_handle_put() on the returned fwnode pointer. " Add fwnode_handle_put() to avoid a leaked reference.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).
