UBUNTU-CVE-2025-38662: High severity ubuntu/linux-hwe-edge vulnerability
In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8365-dai-i2s: pass correct size to mt8365daisetpriv Given mt8365daisetpriv allocate privsize space to copy privdata which means we should pass mt8365i2spriv[i] or "struct mtkafei2spriv" instead of afepriv which has the size of "struct mt8365afeprivate". Otherwise the KASAN complains about. [ 59.389765] BUG: KASAN: global-out-of-bounds in mt8365daisetpriv+0xc8/0x168 [sndsocmt8365pcm] ...

Pass mt8365_i2s_priv[i] or a struct mtk_afe_i2s_priv object to mt8365_dai_set_priv instead of afe_priv, because the function allocates priv_size space to copy priv_data.
Linux kernel ASoC MediaTek MT8365 DAI I2S priv_data argument to mt8365_dai_set_priv = mt8365_i2s_priv[i] or struct mtk_afe_i2s_priv
