CVE-2025-39930: ASoC: simple-card-utils: Don't use __free(device_node) at graph_util_parse_dai()

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.26% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 146e25625378f7d4463acbd1ffbd975f3332a806, 16a49e3fda339aa552cde7f2cdbb25b91426cb8a, 232a32e8a7e9be8a2ee238df9b5304eed2f4e195.
  • Severity is disputed: the assigning authority (CNA) scores it 8.4, NVD 5.5.

Low priority for now. Upgrade to Linux Linux 146e25625378f7d4463acbd1ffbd975f3332a806, 16a49e3fda339aa552cde7f2cdbb25b91426cb8a, 232a32e8a7e9be8a2ee238df9b5304eed2f4e195 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ASoC: simple-card-utils: Don't use __free(device_node) at graph_util_parse_dai() commit 419d1918105e ("ASoC: simple-card-utils: use __free(device_node) for device node") uses __free(device_node) for dlc->of_node, but we need to keep it while driver is in use. Don't use __free(device_node) in graph_util_parse_dai().
