CVE-2026-90068 — ASoC: dapm: Fix off-by-one check on the second enum channel

In the Linux kernel, the following vulnerability has been resolved: ASoC: dapm: Fix off-by-one check on the second enum channel The snd_soc_dapm_put_enum_double() rejects item[0] once it reaches e->items, but it lets item[1] be equal to it. Both go on to snd_soc_enum_item_to_val(), which indexes e->values with no bound of its own, so an enum with a value table reads one element past the end. The indexing arrived with the MUX consolidation, which relaxed the item[1] check in the same hunk. The value MUX handler it deleted used >= there, and the snd_soc_put_enum_double() in soc-ops.c still does. Only adav80x pairs a value table with two shifts, and its second channel looks accidental, but the control does report two values. Writing three into it reads off the end of adav80x_mux_values. The core catches that only under CONFIG_SND_CTL_INPUT_VALIDATION, which defaults off.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.2% (30-day exploitation probability)+2

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.
