NewCVE-2026-90068 (opens in a new tab)How to fix?
Upgrade Debian:12 linux-6.12 to version 6.12.111-1~deb12u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream linux-6.12 package and not the linux-6.12 package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
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.
