CVE-2026-64243

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the ASoC codecs simple-mux component where the simple mux control put() function fails to properly validate enum control bounds. Because enum control values are zero-based, the function incorrectly accepts values equal to e->items, which should be rejected. This can lead to the storage of an invalid mux state, which is then passed to the GPIO setter and the DAPM mux update path, where it is used as an index into the enum text array.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
