📄 Description (English)

A flaw was found in the X.Org X server. This out-of-bounds read vulnerability in the XKB geometry processing, specifically within the `CheckSetGeom()` and `XkbAddGeomKeyAlias` functions, allows an attacker to read uninitialized or out-of-bounds memory. An attacker with a connection to the X11 server, either locally or remotely, can exploit this without user interaction. This could lead to the disclosure of memory contents or cause a denial of service by crashing the server.

🤖 AI Executive Summary

An out-of-bounds read vulnerability exists in X.Org X server's XKB geometry processing functions, allowing attackers to read sensitive memory or crash the server. Exploitation requires X11 server connection but no user interaction.

📄 Description (Arabic)

ثغرة قراءة خارج الحدود في دوال CheckSetGeom و XkbAddGeomKeyAlias بخادم X.Org تسمح بالوصول إلى ذاكرة غير مهيأة. يمكن للمهاجمين المتصلين بخادم X11 محليًا أو عن بعد استغلال هذه الثغرة دون تفاعل المستخدم.

🤖 ملخص تنفيذي (AI)
