Description
CVE-2026-35201 is an out-of-bounds read vulnerability in the rdiscount Markdown parser (versions >= 1.3.1.1 and < 2.2.7.4). It arises from a signed length truncation bug where inputs larger than INT_MAX are truncated before parsing, causing the parser to read beyond the buffer and potentially crash. This issue affects availability but does not impact confidentiality or integrity. The vulnerability is fixed in version 2.
