CVE-2026-120060
Description
A flaw was found in psqlODBC. The driver improperly validates lengths and counts received from the database server across multiple data handling operations. A malicious or compromised server can exploit this vulnerability by returning crafted responses to a connecting client. Successful exploitation can result in a Denial of Service (DoS) by crashing the client application, or lead to an out-of-bounds memory read.
Statement
This vulnerability is rated as having Moderate impact for Red Hat products because exploitation requires a client application to connect to a malicious or compromised database server, or an untrusted endpoint over an unverified connection. In standard enterprise environments, applications utilizing psqlODBC connect strictly to managed, authenticated database infrastructure, restricting untrusted exposure. Furthermore, the maximum blast radius is limited to client-side process termination or out-of-bounds memory reading, with no capability for remote code execution or modification of system data.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Memory
An attacker could get secret values such as cryptographic keys, PII, memory addresses, or other information that could be used in additional attacks.
Confidentiality
Technical Impact: Bypass Protection Mechanism
Out-of-bounds memory could contain memory addresses or other information that can be used to bypass ASLR and other protection mechanisms in order to improve the reliability of exploiting a separate weakness for code execution.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An attacker could cause a segmentation fault or crash by causing memory to be read outside of the bounds of the buffer. This is especially likely when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string.
Other
Technical Impact: Varies by Context
The read operation could produce other undefined or unexpected results.
