CVE-2026-95117 Details
Description
Buffer Overflow vulnerability in zserge jsmn jsmn HEAD 25647e6 allows a remote attacker to cause a denial of service via the jsmn.h, jsmn_parse(), example/jsondump.c, dump() components
A buffer overflow vulnerability has been identified in Zserge Jsmn, specifically in the HEAD commit 25647e6. This vulnerability allows remote attackers to cause a denial-of-service by exploiting the JSON parsing functionality. The issue arises in the non-strict parser of Jsmn, where malformed JSON can lead to an incorrect token tree. This misrepresentation allows the example JSON dump utility to read beyond the allocated token array, potentially disclosing memory and causing a heap-buffer-overflow error.
Users can update to the latest version of Zserge Jsmn, which includes a fix for this vulnerability. The fix is available in the 'zserge/jsmn' repository on GitHub.
