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-2026-50256

A stack-based buffer overflow flaw was found in the X.Org X server and Xwayland. A mismatch between the X server and the libXfont2 library's maximum font name length can cause a stack buffer overflow during font alias resolution. The server allocates a 256 byte stack buffer but libXfont2's alias...

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...
