Doc Text:
A flaw was found in libdisplay-info. A local attacker can cause a Denial of Service (DoS) by providing specially crafted Extended Display Identification Data (EDID) through a malicious display, video capture device, or file. The DisplayID parser fails to properly validate data block lengths, allowing the parser to read past the allocated buffer and crash the application.

Description OSIDB Bzimport 2026-10-19 14:18:20 UTC
Libdisplay-info 0.4.0 contains a heap out-of-bounds read vulnerability in the DisplayID v2 section parser in displayid2.c that allows attackers to read past the EDID buffer via oversized data block lengths. Attackers can supply a crafted EDID from a malicious monitor, KVM, capture device, or file to over-advance the parse cursor and crash applications.
