CVE-2026-50259

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-2026-50258

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...

CVE-2026-50256

The CVE affects the X.Org X server and Xwayland. A mismatch between the server and libXfont2 regarding maximum font name length (server-allocated 256-byte stack buffer vs libXfont2 name length up to 1024 bytes) allows a font alias name of 257–1023 bytes to overflow the stack during alias resoluti...
