Description OSIDB Bzimport 2025-08-22 17:03:18 UTC
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.
