CVE-2024-58012 is a NULL pointer dereference vulnerability in the Linux kernel ASoC Sound Open Firmware (SOF) Intel HDA digital audio interface (DAI) implementation. Each CPU DAI is expected to have an associated DAI widget, but audio topologies using aggregated amplifiers may fail to create the required number of widgets. Parameter handling can then dereference a missing widget, potentially crashing the kernel or disrupting the affected audio path. The fix validates the associated widget before use.

A NULL pointer dereference vulnerability in the Linux kernel's ASoC SOF Intel hda-dai component. Audio topologies with aggregated amplifiers may lack required DAI widgets, causing a dereference during parameter handling. The advisory rates it Medium, with CVSS v3 5.5, indicating local exploitation requiring low privileges and potentially high availability impact.
