Summary

CVE-2025-26597 is a buffer overflow vulnerability affecting X.Org and Xwayland. The issue arises when XkbChangeTypesOfKey() is called with a group value of 0, causing the key symbols table to be resized to zero. Subsequent calls to XkbChangeTypesOfKey() with non-zero group values result in a buffer overflow due to the inconsistent size of the key actions. This vulnerability can potentially be exploited by attackers to execute arbitrary code or cause a system crash. It is recommended that users apply the available patches to mitigate this risk.
