How to fix?

Upgrade Oracle:8 libslirp to version 0:4.4.0-2.module+el8.10.0+90960+1362bdc4 or higher.
This issue was patched in ELSA-2026-38504.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libslirp package and not the libslirp package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil.
