This issue was fixed by the following commit (upstream as of the 6.9 kernel):
1560d1f6eb6b398bddd80c16676776c0325fe5fe "sched/eevdf: Prevent vlag from going out of bounds in reweight_eevdf()"
I've sent the patches to the mailing list for noble:linux (https://lists.ubuntu.com/archives/kernel-team/2024-June/151360.html). I left out other derivatives as they'll get them from noble:linux. Oracular is tracking past the 6.9 kernel, so these patches should already be applied there.
I've also attached the bisect logs for the break and fix commits, as well as the script used to test (along with a patch to speed up testing).
