CVE-2026-80910

Summary: ASoC: codecs: lpass-wsa-macro: Fix enum kcontrol accesses

Details: In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: lpass-wsa-macro: Fix enum kcontrol accesses EAR SPKR PA Gain" and the four "WSA RX* Mux" controls are enumerated, but their get and put callbacks access the 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 wsa-macro was missed. On 64-bit kernels with CONFIG_SND_CTL_DEBUG this trips the elem value sanity check and every read of these controls fails with -EINVAL.
