  Solar flares are regularly detected by the Large Area Telescope (LAT) on
board the Fermi satellite, however no gamma-ray emission from other stellar
eruptions has ever been captured. The Swift detection in April 2014 of a
powerful outburst originating from DG CVn, with associated optical and radio
emissions, enticed us to search for possible 0.1-100 GeV emission from this
flaring nearby binary star using the Fermi/LAT. No gamma-ray emission is
detected from DG CVn in 2014, but we report a significant gamma-ray excess in
November 2012, at a position consistent with that of the binary. There are no
reports of contemporary flaring at other wavelengths from DG CVn or any other
source within the error circle of the gamma-ray source. We argue that the
gamma-ray flare is more likely to have been associated with a background blazar
than with DG CVn and identify a candidate for follow-up study.
