CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's ASoC (ALSA System on Chip) subsystem, specifically within the simple-mux codec driver, where improper bounds checking allows invalid enum control values to be accepted. This flaw can lead to the storage of an invalid mux state, potentially causing system instability or unexpected behavior during audio processing. Organizations utilizing Linux systems with audio processing capabilities should prioritize patching this vulnerability to mitigate risks associated with audio control misconfigurations.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: simple-mux: Fix enum control bounds check simple_mux_control_put() rejects values greater than e->items, but enum control values are zero based. For the two-entry mux used by this driver, valid values are 0 and 1, so value 2 must be rejected as well. Accepting e->items can store an invalid mux state, pass it to the GPIO setter, and pass it on to the DAPM mux update path where it is used as an index into the enum text array. Use the same >= e->items check used by the ASoC enum helpers.
