About this tag
A parsing bug is a software defect in code that interprets structured data, such as JSON or device commands, leading to incorrect behavior. On WindowsForum.com, discussions cover parsing bugs in Linux kernel drivers and the cJSON library. One thread details CVE-2025-68308, an off-by-one error in the Kvaser USB CAN driver's command parser that can cause an infinite loop and local denial-of-service. Another covers CVE-2023-26819, a parsing defect in cJSON version 1.7.15 triggered by crafted JSON documents, resulting in denial-of-service. These examples highlight how parsing bugs can affect reliability and security, often requiring patches to prevent crashes or resource exhaustion.
