AlmaLinux 8.8: linux-firmware package fails signature check

When a system failed updating due to a checksum problem with the linux-firmware package, I downloaded the rpm file manually from the repository and from one mirror. Both rpm files failed the check:

rpm --checksig linux-firmware-20230404-117.git2e92a49f.el8_8.alma.1.noarch.rpm
linux-firmware-20230404-117.git2e92a49f.el8_8.alma.1.noarch.rpm: DIGESTS SIGNATURES NOT OK

Is there a problem in the build?
