UBUNTU-CVE-2024-58012: Medium severity ubuntu/linux-hwe-edge vulnerability

Q: Who is most likely to be exposed to this issue?

Systems using the listed Ubuntu kernel packages and Intel SOF HDA audio with topologies for aggregated amplifiers are the relevant population. The failure condition involves CPU DAIs whose associated widgets are missing from the audio topology.

Q: What access does an attacker need to trigger the issue?

The severity vector indicates local access and low privileges are required, with no user interaction. The impact is availability only: the missing widget can cause a NULL-pointer dereference and system crash.

Q: Is there a configuration-based mitigation if an updated kernel cannot be deployed immediately?

The provided information identifies the affected condition as an Intel SOF HDA topology with aggregated amplifiers and missing DAI widgets. Avoiding use of that affected audio topology may reduce exposure, but no specific supported workaround is provided.

Updated

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Intel: hda-dai: Ensure DAI widget is valid during params Each cpu DAI should associate with a widget. However, the topology might not create the right number of DAI widgets for aggregated amps. And it will cause NULL pointer deference. Check that the DAI widget associated with the CPU DAI is valid to prevent NULL pointer deference due to missing DAI widgets in topologies with aggregated amps.
