EUVD-2026-34814

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. XkbSetMapChecks declares a fixed-size stack buffer mapWidths256 indexed by key type index. The helper function CheckKeyTypes writes to this buffer at a client-controlled offset, allowing a stack buffer overflow. This...

CVE-2026-50259

The CVE-2026-50259 entry describes a stack-based buffer overflow in X.Org X server and Xwayland. The vulnerability centers on XkbSetMapChecks(), which declares a fixed-size buffer mapWidths[256] on the stack and is indexed by key type. CheckKeyTypes() writes to this buffer at a client-controlled ...

CVE-2026-50258

The CVE affects the X.Org X server and Xwayland. A stack-based buffer overflow arises from unchecked key-type shift levels in XkbKeyTypes: multiple stack buffers sized XkbMaxShiftLevel * XkbNumKbdGroups are not clamped by CheckKeyTypes(), allowing a client to set excessive shift levels and trigge...

CVE-2026-50258

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. The X server has multiple stack buffers sized XkbMaxShiftLevel XkbNumKbdGroups but CheckKeyTypes does not verify or clamp non-canonical key types to XkbMaxShiftLevel. A client can change key types to excessive shift...
