CVE ID :CVE-2026-80583

Description :In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: lpass-tx-macro: Fix enum kcontrol accesses The "DEC0 MODE" to "DEC7 MODE" controls are enumerated, but tx_macro_dec_mode_get() and tx_macro_dec_mode_put() access their value through ucontrol->value.integer.value[0] (a long) instead of ucontrol->value.enumerated.item[0] (an unsigned int). This same pattern was fixed in the sibling drivers by commit bcfe5f76cc40 ("ASoC: codecs: rx-macro: fix accessing array out of bounds for enum type") and commit 0ea5eff7c606 ("ASoC: codecs: va-macro: fix accessing array out of bounds for enum type"), but tx-macro was missed. On 64-bit kernels built with CONFIG_SND_CTL_DEBUG, the elem value sanity check catches the 4 bytes written past the enumerated item and every read of these controls fails with -EINVAL: snd-sm8250 sound: control 2:0:0:DEC0 MODE:0: access overflow
Severity: 0.0 | NA
