+Subject: [PATCH] xkb: Fix buffer overflow in _XkbSetCompatMap()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The _XkbSetCompatMap() function attempts to resize the `sym_interpret`
+buffer.
+
+However, It didn't update its size properly. It updated `num_si` only,
+without updating `size_si`.
+
+This may lead to local privilege escalation if the server is run as root
+or remote code execution (e.g. x11 over ssh).
+
+CVE-2024-9632, ZDI-CAN-24756
+
+This vulnerability was discovered by:
+Jan-Niklas Sohn working with Trend Micro Zero Day Initiative
