CVE-2024-39473 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc4-topology: Fix input format query of process modules without base extension If a process module does not have base config extension then the same format applies to all of it's inputs and the process->base_config_ext is NULL, causing NULL dereference when specifically crafted topology and sequences used.. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
