https://access.redhat.com/errata/RHSA-2026:56984 reports:
A flaw was found in popt. This vulnerability allows an attacker
to provide specially crafted configuration content to a host, which,
when loaded, can lead to a small memory corruption issue. This
occurs because of an error in how the `poptConfigFileToString`
function reallocates memory for buffers. Successful exploitation
could result in heap metadata corruption, potentially causing the
affected process to become unavailable (denial of service).
