CVE-2026-50144

ncnn is a high-performance neural network inference framework optimized for the mobile platform. In commit e54f7b1f88434e1d844ea0551b880a1cfb079ce1 and earlier, ncnn allows an out-of-bounds heap write in ncnn::ParamDict::load_param() when Net::load_param() loads a malicious .param model file because the parsed parameter id is checked only against id >= NCNN_MAX_PARAM_COUNT, allowing a negative id to index before the params[NCNN_MAX_PARAM_COUNT] array. This vulnerability is fixed by commit 5a0288f255daa6c3294f77109f67718e434ec020.

Summary		(es) ncnn es un framework de inferencia de redes neuronales de alto rendimiento optimizado para la plataforma móvil. En el commit e54f7b1f88434e1d844ea0551b880a1cfb079ce1 y anteriores, ncnn permite una escritura fuera de límites en el heap (out-of-bounds heap write) en ncnn::ParamDict::load_param() cuando Net::load_param() carga un archivo de modelo .param malicioso porque el ID del parámetro analizado se verifica solo contra id >= NCNN_MAX_PARAM_COUNT, lo que permite que un ID negativo indexe antes del array params[NCNN_MAX_PARAM_COUNT]. Esta vulnerabilidad se corrige con el commit 5a0288f255daa6c3294f77109f67718e434ec020.
