CVE-2026-32316

A flaw was found in jq, a command-line JSON processor. An attacker can exploit an integer overflow vulnerability by crafting queries that produce extremely large strings. This causes a 32-bit unsigned integer overflow in the buffer allocation size calculation, leading to a drastically undersized memory buffer. Subsequent memory copy operations then write the full string data into this undersized buffer, causing a heap-based buffer overflow. This can result in a Denial of Service (DoS) by crashing the process or potentially allow for further exploitation through heap corruption.
