Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.69%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
"" In X.Org X Server 1.20.4, there is a stack-based buffer overflow in the function XQueryKeymap. For example, by sending ct.c_char 1000 times, an attacker can cause a denial of service (application crash) or possibly have unspecified other impact. Note: It is disputed if the X.Org X Server is involved or if there is a stack overflow.
