CVE-2026-19395

An empty <img> attribute value in styled text triggers a parser error that halts the device. PUBLISHED

Description (CNA)

In Qt for MCUs, a Text element that displays styled text halts the device if an <img> tag in the text contains an attribute with an empty value. The text parser passes the empty value to an internal check that only accepts non-empty values. The check fails and reports an error, and the default error handler halts the device.
