X.org Server Flaw Allows Buffer Overflow, Denial of Service or Privilege Escalation

CVE-2024-9632

Summary

A flaw exists in the X.org server that stems from an improper handling of allocation size in the _XkbSetCompatMap function. This vulnerability allows a local attacker to potentially exploit this issue by sending a specially crafted payload, which could result in a buffer overflow condition. If successfully exploited, this vulnerability may lead to denial of service or enable local privilege escalation in environments where the X.org server operates with elevated permissions, specifically with root access. It is crucial for administrators to review their configurations and apply necessary security updates to mitigate the risks associated with this vulnerability.
