Comment 5 for bug 2038583

My analysis based on public information is that 31bit binaries that are compiled against glibc 2.31 or earlier might be affected. Something like db2 version 9.7, 31bit s390 edition of it. Which is well out of support, and not sure if it was ever possible to run on Ubuntu.

Separately, please let me know if we still need to keep support for 31bit binaries on Ubuntu - as turning off CONFIG_COMPAT for 31bit binaries, and dropping compilation of biarch binaries will harden kernel & userspace, as well as ensure that s390x port is year 2038 ready ahead of x86.
