Fixed in Fedora rawhide (f45) via erlang-27.3.4.14-1.fc45, which ships the upstream OTP fix (erts-15.2.7.9, in OTP 27.3.4.13). f43 and f44 remain on the OTP 26.x line, which did not receive an upstream fix for this issue, so a downstream backport is required. Backports for f43/f44 are prepared; updates will follow via Bodhi. FEDORA-2026-dcf80dc1ff (erlang-26.2.5.21-4.fc44) has been submitted as an update to Fedora 44. https://bodhi.fedoraproject.org/updates/FEDORA-2026-dcf80dc1ff FEDORA-2026-965be97ac0 (erlang-26.2.5.21-4.fc43) has been submitted as an update to Fedora 43. https://bodhi.fedoraproject.org/updates/FEDORA-2026-965be97ac0 FEDORA-2026-dcf80dc1ff has been pushed to the Fedora 44 testing repository.
