GHSA-6G4P-43G8-PPPH
Vulnerability from github – Published: 2025-08-22 18:31 – Updated: 2025-11-26 00:30In 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.
