What the source says
Referenced, awaiting primary-source reviewAdopted on 21 September 1964. [The Roger I of Sicily tradition is] debunked as a 19th-century myth [with] the Knights of Malta's flag (white cross on red field) a more likely source. King George VI awarded the George Cross to Malta on April 15, 1942 in recognition of its courageousness during World War II; the cross was officially added to the flag on December 28, 1943. [The article gives no official meaning for the colours.]

Colors
Symbolism and history(r1)
A white-over-red bicolor, its colours most likely drawn from the flag of the Knights of Malta rather than the 19th-century myth of Roger I of Sicily, bears the George Cross in the upper hoist — the British gallantry award given to the whole island in 1942 for its endurance in the Second World War, added to the flag in 1943.
