We have investigated the polarization of attosecond light bursts generated bynanobunches of electrons from relativistic few-cycle laser pulse interactionwith the surface of overdense plasmas. Particle-in-cell simulation shows thatthe polarization state of the generated attosecond burst depends on theincident-pulse polarization, duration, carrier envelope phase, as well as theplasma scale length. Through laser and plasma parameter control, withoutcompromise of generation efficiency, a linearly polarized laser pulse withazimuth $\theta^i=10^\circ$ can generate an elliptically polarized attosecondburst with azimuth $|\theta^r_{\rm atto}|\approx61^\circ$ and ellipticity$\sigma^r_{\rm atto}\approx0.27$; while an elliptically polarized laser pulsewith $\sigma^i\approx0.36$ can generate an almost circularly polarizedattosecond burst with $\sigma^r_{\rm atto}\approx0.95$. The results propose anew way to a table-top circularly polarized XUV source as a probe withattosecond scale time resolution for many advanced applications.
