On Monday, the International Olympic Committee released a statement declaring that re-testing of Chernova's samples from Beijing revealed the prohibited substance turinabol.
Sotherton had previously been upgraded from fifth to fourth when silver medallist Lyudmila Blonska of Ukraine was stripped and banned for life following a second positive test.
Jessica Ennis-Hill has one last goal in elite athletics.
Chernova's is the 18th Russian doping case from the Beijing Olympic revealed in a re-testing program that has mostly relied on improved detection of steroids.
Therefore, Sotherton got a unique chance to become a back-to-back Olympic heptathlon medal holder almost nine years after following up her fifth place with bronze, which upgraded just a week later to fourth when Ukraine's Lyudmyla Blonska was caught doping.
Shock over 'mass arrests' of gays in Chechnya
In interviews with gay men who later fled Chechnya , Lokshina said some "returned to their families barely alive from beatings". Chechnya's president has reportedly vowed to eradicate the republic's gay community before the start of Ramadan.
Nine years is a long time to wait for an Olympic medal, but when it does come along, it looks like it feels pretty good.
Meanwhile, Russian 400 metre runner Maksim Dyldin has also been disqualified from the London Games after his retested sample was found to contain the same steroid as Chernova's.
It means Briton Kelly Sotherton, who originally finished fifth in the Beijing Games, now stands to be awarded the bronze medal.
Dyldin finished 17th in the 400m in London and helped Russian Federation to fifth in the 4x400m relay - those results have been annulled.
The IOC has now caught 111 athletes through retesting from the 2008 and 2012 Games.
