CVE-2026-4046  (opens in a new tab)

How to fix?

Upgrade Echo:latest glibc to version 2.36-9+deb12u14 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream glibc package and not the glibc package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

The iconv() function in the GNU C Library versions 2.43 and earlier may crash due to an assertion failure when converting inputs from the IBM1390 or IBM1399 character sets, which may be used to remotely crash an application.

This vulnerability can be trivially mitigated by removing the IBM1390 and IBM1399 character sets from systems that do not need them.
