Doc Text:	A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey() is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size.	Story Points:	---

Description OSIDB Bzimport 2025-02-12 14:23:50 UTC

If XkbChangeTypesOfKey() is called with 0 group, it will resize the key
symbols table to 0 but leave the key actions unchanged.

If later, the same function is called with a non-zero value of groups,
this will cause a buffer overflow because the key actions are of the wrong
size.
