Comment 1 Peter Lemenkov 2026-07-10 16:24:55 UTC
Fixed in Fedora rawhide (f45) via erlang-27.3.4.14-1.fc45, which ships the upstream OTP fix (ssl-11.2.12.9, 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.
