Cameron, 37, was sentenced to a five-year prison term for possession of heroin and methamphetamine in 2010.
After he confessed to smuggling drugs into prison, his sentence was extended and he spent two years in solitary confinement at Maryland's Cumberland Federal Corrections Institute, reported People magazine.
He was scheduled for release in 2018, but is now living in a halfway house in Brooklyn, New York.
Cameron is son of Douglas, 71, from his ex-wife Diandra. They divorced in 2000 after 23 years of marriage.
