CVE-2025-63701
Last modified
CVE-2025-63701 is a medium-severity vulnerability rated 6.8/10 on the CVSS scale. A heap corruption vulnerability exists in the Advantech TP-3250 printer driver's DrvUI_x64_ADVANTECH.dll (v0.3.9200.20789) when DocumentPropertiesW() is called with a valid dmDriverExtra value but an undersized output buffer. The driver incorrectly assumes the output buffer size matches the input buffer size, leading to invalid memory operations and heap corruption. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
