Vulnerabilidad en kernel de Linux (CVE-2025-38662)

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: mediatek: mt8365-dai-i2s: pasar el tamaño correcto a mt8365_dai_set_priv. Dado mt8365_dai_set_priv, se asigna espacio priv_size para copiar priv_data, lo que significa que debemos pasar mt8365_i2s_priv[i] o "struct mtk_afe_i2s_priv" en lugar de afe_priv, cuyo tamaño es "struct mt8365_afe_private". De lo contrario, la queja de KASAN. [ 59.389765] ERROR: KASAN: global fuera de los límites en mt8365_dai_set_priv+0xc8/0x168 [snd_soc_mt8365_pcm] ...
