CVE-2026-110654 · libzvbi through 0.2.45 Out-of-Bounds Write via Teletext DRCS convert_drcs

This page contains facts from public vulnerability sources. Check the original advisory before updating.

libzvbi through 0.2.45 contains an out-of-bounds write vulnerability in the Teletext decoder that allows attackers to corrupt memory by supplying unvalidated DRCS pixel-mode values in X/28/3 packets. Attackers can send a crafted Teletext stream decoded via vbi_decode with every slot set to DRCS_MODE_6_5_4, causing convert_drcs to overflow chars[48][60] and crash the application.
