En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: smb: cliente: garantiza que los hijos recontados desde la sesión principal Evite posibles errores de use after free al recorrer referencias DFS, montar y realizar la conmutación por error de DFS asegurándose de que todos los hijos del padre @tcon- >ses también se cuentan nuevamente. Todos son necesarios en todo el montaje DFS. Deshazte de @tcon->dfs_ses_list mientras estamos en eso también.
