CVE-2026-120064: psqlODBC Missing Bounds Validation

Sources read

Source agreement

Tam uyum

Evidence confidence

%55

Short explanation

psqlODBC contains an out-of-bounds read and write vulnerability due to failing to validate column numbers and row indexes according to sources S0 and S1.

Why does it matter?

Applications forwarding untrusted column or row numbers expose their processes to out-of-bounds reads and writes (S0, S1).

What should be done?

  • Follow the vendor security advisory (S0)
  • Update psqlODBC versions (S0, S1)
Chain of evidence and sources2 verified claims

Show the technical text from the sources

Several psqlODBC entry points use an application-supplied column number or row index as an array index without validating it. SQLBindCol with a column number above 32767 wraps the binding count negative and a later copy runs off the array. A negative SQL_DESC_COUNT on an application row descriptor unbinds columns at negative indexes. SQLColAttribute with a very large column number uses a negative index. SQLSetPos(SQL_ADD) does not check the row number against the rowset size. An application that forwards untrusted column or row numbers exposes its process to out-of-bounds reads and writes. Versions before psqlODBC 18.00.0006 are affected.

Confirm the affected product and version against the source evidence above.
Restrict access to internet-facing services and apply network segmentation.
Until a patch is confirmed, follow the vendor advisory; do not read an unknown status as “no patch”.
Monitor server logs and network endpoints for signs of anomalous execution.
