CVE-2026-55999 HIGH 7.8

Local privilege escalation via heap buffer overflow in the X.Org Server (versions before 21.1.24) and Xwayland (before 24.1.13) allows a local user holding an X connection to corrupt heap memory by supplying a malicious PCX font. The flaw lives in the SetFont code path, where missing glyph boundary checks let an oversized or malformed glyph write past its heap allocation, yielding full confidentiality, integrity, and availability impact (CVSS 7.8). There is no public exploit identified at time of analysis; EPSS is low at 0.28% and CISA SSVC rates exploitation as none.
