CVE-2026-112271: libdisplay-info heap out-of-bounds read in DisplayID parser

CVE-2026-112271 · Severity: medium · CVSS 5.5 · Published 2026-10-19

libdisplay-info is a library that parses EDID and DisplayID data from monitors and display devices. A flaw in the DisplayID v1 section parser allows a malicious monitor, KVM, or capture device to send a crafted display configuration that causes the library to read past allocated memory, potentially crashing applications that use it.

Vendors: Freedesktop.

Technical details

A heap out-of-bounds read vulnerability exists in the displayid.c file where the is_all_zeroes function reads past the buffer boundary when a data block's declared length exceeds the section size. An attacker can craft a malicious EDID file or provide one via a physical display device, KVM, or video capture device to trigger this read, causing denial of service through a crash.
