Summary
In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8365-dai-i2s: pass correct size to mt8365_dai_set_priv Given mt8365_dai_set_priv allocate priv_size space to copy priv_data which means we should pass mt8365_i2s_priv[i] or "struct mtk_afe_i2s_priv" instead of afe_priv which has the size of "struct mt8365_afe_private". Otherwise the KASAN complains about. [ 59.389765] BUG: KASAN: global-out-of-bounds in mt8365_dai_set_priv+0xc8/0x168 [snd_soc_mt8365_pcm] ...
