Exploitation requires local SNDRV_CTL_IOCTL_ELEM_READ or SNDRV_CTL_IOCTL_ELEM_WRITE on /dev/snd/controlC* through snd_ctl_ioctl() to tx_macro_dec_mode_get/put(); the Qualcomm LPASS TX macro audio codec driver has no network, Bluetooth, or physical-input attack path.\nAC:L - A single ioctl targeting DEC0-7 MODE deterministically triggers the 8-byte integer access against a 4-byte enumerated field on 64-bit kernels; the attacker controls both sides with no race, timing, or memory-layout dependency.\nPR:L - snd_ctl_open() performs no capability check; exploitation needs only local access to /dev/snd/controlC*, typically granted to the audio group on Qualcomm sc8250/sc8280 Chromebooks and Linux dev boards where this driver is present, not real root.\nUI:N - Once the attacker has ALSA control-device access they issue elem read/write ioctls themselves to DEC MODE controls; no separate victim action such as plugging hardware or opening a file is required.\nS:U - The out-of-bounds ctl-value access and resulting microphone ADC mode corruption remain within the host kernel and Qualcomm audio subsystem; there is no crossing of VM, container, or IOMMU security boundaries.\nC:H - tx_macro_dec_mode_put() reads ucontrol->value.integer.value[0] (8 bytes) for ENUM controls, performing a 4-byte out-of-bounds read past enumerated.item[0]; per kernel CVSS guidance out-of-bounds reads are scored High even when bounded.\nI:H - tx_macro_dec_mode_get() writes 8 bytes via integer.value[0], overflowing enumerated.item[0] by 4 bytes in kernel memory; put stores values into tx->dec_mode[] that program CDC_TXn_ADC_MODE on phone/Chromebook microphones, constituting memory corruption scored High.\nA:H - With CONFIG_SND_CTL_DEBUG every DEC0-7 MODE read fails with -EINVAL (access overflow), denying microphone ADC queries; on production 64-bit aarch64 builds the 4-byte union overrun corrupts ctl values and can break Qualcomm LPASS TX audio capture
