CVE-2026-94282: CWE-125 Out-of-bounds read in x.org libXi
An out-of-bounds read in libXi's XI2 enter/leave/focus cookie conversion in libXi before 1.8.4 could be used by malicious X server to crash an attached X client.
AI Analysis
Technical Summary
This vulnerability involves an out-of-bounds read in libXi's XI2 enter/leave/focus cookie conversion code. Versions of libXi prior to 1.8.4 are affected. Exploitation requires a malicious X server interacting with an X client using the vulnerable libXi version, potentially causing the client to crash due to memory access outside intended bounds.
Potential Impact
The primary impact is a denial of service condition where an X client crashes when connected to a malicious X server. There is no indication of confidentiality or integrity compromise. The CVSS score of 5.6 reflects a medium severity with local attack vector, low complexity, and user interaction required.
Mitigation Recommendations
Upgrade libXi to version 1.8.4 or later where this vulnerability is fixed. No other mitigation details or vendor advisories are provided, so patching is the recommended action.
