CVE-2025-5683· NVD / CVE Program· CNA TQtC

When loading a specifically crafted ICNS format image file in QImage then it will trigger a crash.

Noroxi assessment

Priority: Monitor (action score 20/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: Qt Qt 6.5.10.

Low priority for now. Upgrade to Qt Qt 6.5.10 or later.
