CVE-2026-43478: ASoC: codecs: rt1011: Use component to get the dapm context in spk_mode_put

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: 0.10% (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 30e4b2290cc2a8d1b9ddb9dcb9c981df1f2a7399, b10b2b15b45923ff2807eeb034d91a39b0a3e690.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 30e4b2290cc2a8d1b9ddb9dcb9c981df1f2a7399, b10b2b15b45923ff2807eeb034d91a39b0a3e690 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: rt1011: Use component to get the dapm context in spk_mode_put The correct helper to use in rt1011_recv_spk_mode_put() to retrieve the DAPM context is snd_soc_component_to_dapm(), from kcontrol we will receive NULL pointer.
