This can be reproduced locally by running the test in the x/vulndb module located in the module cache, rather than a git repository checkout. For example:

$ cd $(mktemp -d)
$ go mod init example
go: creating new go.mod: module example
$ go get -t golang.org/x/vulndb
go: added golang.org/x/vulndb v0.0.0-20240925174358-74aba449dd50
$ go test golang.org/x/vulndb/internal/symbols

This particular failure wasn't reported by builders until #65267 was resolved. Since it's a pre-existing issue, x/vulndb was opted out in crrev.com/c/5889407.
