Local data disclosure and service interrupt
Published Jul 5, 2026 · Updated Jul 5, 2026
Buffer overflow in TÜBİTAK BİLGEM's Pardus Pen 4.1.5 and earlier allows local users to read data and interrupt the application. The published advisory attributes the overflow to improper null termination but does not identify the affected input, buffer, or code locus. Exploitation requires low local privileges and user interaction; reported effects are limited to data disclosure and an application service interrupt.
