CVE-2026-43478 Details
Description
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.
A vulnerability in the Linux kernel's ASoC (ALSA System on Chip) component for RT1011 codecs has been addressed. The issue arose because the wrong helper function was used to retrieve the DAPM (Dynamic Audio Power Management) context, leading to a NULL pointer dereference. This vulnerability affected the stable versions of the Linux kernel.
Users can upgrade to the latest stable version of the Linux kernel to address this vulnerability. The specific commit that resolves the issue is available in the Linux kernel stable tree.
