DescriptionCVE.org

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.

AnalysisAI

Improper bounds checking in the Linux kernel's ASoC simple-mux driver allows a local attacker with low privileges to cause an out-of-bounds array index, leading to kernel memory disclosure and system crash. The driver erroneously accepts the maximum enum value (2) as valid for a two-entry mux, enabling an invalid mux state to propagate into GPIO and DAPM operations. Vendor patches are available for affected stable kernels, and no public exploit or active exploitation is known at this time.
