Summary
IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.4 for Linux, UNIX and Windows (includes Db2 Connect Server) could allow an authenticated user to cause a denial of service due to improper neutralization of special elements in data query logic.
Risk Assessment
An authenticated user could cause database unavailability, disrupting business applications. This may lead to service interruptions and operational losses.
Recommendation
Update IBM Db2 to the latest patched version. Restrict user privileges to the minimum necessary.
Other vulnerabilities in IBM Db2
See all- CVE-2015-1935High
The scalar-function implementation in IBM DB2 versions 9.7 through FP10, 9.8 through FP5, 10.1 before FP5, and 10.5 through FP5 on Linux, UNIX, and Windows allows remote attackers to cause a denial of service or execute arbitrary code via unspecified vectors.
- CVE-2014-3094High
IBM DB2 has a stack-based buffer overflow affecting versions 9.7 through FP9a, 9.8 through FP5, 10.1 through FP4, and 10.5 before FP4 on Linux, UNIX, and Windows. This allows remote authenticated users to execute arbitrary code via a crafted ALTER MODULE statement.
- CVE-2014-0907High
Multiple untrusted search path vulnerabilities in setuid and setgid programs in IBM DB2 9.5, 9.7 before FP9a, 9.8, 10.1 before FP3a, and 10.5 before FP3a on Linux and UNIX allow local users to gain root privileges via a Trojan horse library.
- CVE-2013-6744High
The Stored Procedure infrastructure in IBM DB2 versions 9.5, 9.7 before FP9a, 10.1 before FP3a, and 10.5 before FP3a on Windows allows remote authenticated users to gain privileges by leveraging the CONNECT privilege and the CREATE_EXTERNAL_ROUTINE authority.
- CVE-2026-10109Critical
IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.4 are vulnerable to remote code execution due to improper handling of DRDA handshake before authentication.
- CVE-2026-104364Low
IBM Db2 11.5.0 through 11.5.9, and 12.1.0 through 12.1.5 could allow a local attacker to cause a denial of service due to improper input validation.
- CVE-2026-104332Medium
IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 are vulnerable to a denial of service when executing a specially crafted query with a Materialized Query Table.
- CVE-2026-78404Medium
IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 are vulnerable to a local privilege escalation via the db2pd utility.
- CVE-2026-18166High
IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 for Linux, UNIX and Windows (including DB2 Connect Server) could allow a remote authenticated attacker to obtain sensitive information due to improper authorization when using the CREATE WRAPPER command.
- CVE-2026-105466Medium
IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 is vulnerable to a denial of service when inserting into a table with XML columns under specific conditions. The vulnerability can lead to service unavailability.
