Exploitability
| CWE ID | Description |
|---|---|
| CWE-190 | The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-7709 is an integer overflow vulnerability in the SQLite FTS5 extension. It happens when calculating the size of an array of tombstone pointers, where a 64-bit multiplication result is truncated to a 32-bit integer, causing the allocated memory to be too small. This leads to a heap buffer overflow when the program writes a pointer out of bounds in the array. An attacker can exploit this by executing arbitrary SQL queries or providing a malicious SQLite database file. [1]
How can this vulnerability impact me? :
This vulnerability can lead to a heap buffer overflow, which may allow an attacker to write out of bounds in memory. This can cause application crashes, data corruption, or potentially enable remote code execution if exploited successfully. The attacker needs the ability to run arbitrary SQL queries or supply a crafted SQLite database to trigger the issue. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by checking for the presence of vulnerable versions of SQLite with the FTS5 extension. Since the vulnerability is triggered by processing maliciously crafted SQLite database files or executing arbitrary SQL queries, detection involves monitoring for suspicious SQL queries or unexpected SQLite database files. Specific commands to detect vulnerable SQLite versions or scan for malicious files are not provided in the available resources. [1]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include updating SQLite to the fixed version released after July 16, 2025, which properly handles the size calculation to prevent integer overflow. Additionally, restrict or monitor the execution of arbitrary SQL queries, especially those that can manipulate FTS5 tables, and avoid processing untrusted or malicious SQLite database files. [1]
