LibXi Security Update — AlmaLinux 8 (ALSA-2026:93438)

ALSA-2026:93438 updates libXi on AlmaLinux 8, fixing CVE-2026-109090 and CVE-2026-109089 — arbitrary code execution via oversized DEVICE_ENABLE replies from a malicious X server. Update with dnf update libXi and restart X applications; headless servers without X are unaffected.

Часто задаваемые вопросы

What is CVE-2026-109090?

It is an arbitrary code execution flaw in libXi triggered by an oversized DEVICE_ENABLE reply from a malicious X server (oversized-reply class), fixed with CVE-2026-109089 in the AlmaLinux 8 update ALSA-2026:93438.

Who is affected?

Systems running X11 applications that connect to an X server — the client library parses server replies, so the server side is the attack source. Headless servers without X clients are unaffected.

How do I apply the fix?

Run dnf update libXi and restart X applications so they reload the patched library. No reboot required.

Is this part of the X11 library security wave?

Yes — libXrender, libXtst, libX11 and libXi all received fixes in this window; they share protocol-parsing code, so batches land together. Apply all X11 library updates together.
