Malle's degree-matching conjecture for cuspidal characters of finite Chevalley groups

Let $q=p^f$ be a power of the prime $p$, let $G$ be a finite Chevalley group defined over $\mathbb F_q$ with $p$ a bad prime for $G$, and let $U$ be a Sylow $p$-subgroup of $G$. For a character degree $\rho(1)$, write $\rho(1)_p$ for its $p$-part. Malle's conjecture. For every cuspidal character $\rho\in\operatorname{Irr}(G)$, there exists $\chi\in\operatorname{Irr}(U)$ such that

$$\chi(1)=\rho(1)_p.$$

The conjecture predicts a strong connection between cuspidal character degrees of finite groups of Lie type and the degrees of irreducible characters of their Sylow $p$-subgroups, supporting the use of induced characters from $U$ in studying modular representations and decomposition matrices. Its resolution status is not specified in the source.
