CVE-2026-11725
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk35th percentile - higher than 35% of all known CVEs
Summary
IBM MQ could allow an authenticated attacker to cause a denial of service or potentially execute arbitrary code due to an integer overflow in MQINQ request processing.
Risk Assessment
An attacker could disrupt service or gain code execution capability, posing a serious threat to system integrity.
Recommendation
Apply IBM MQ patches and monitor the system for unusual MQINQ requests.

- CVE-2026-11378High
IBM MQ could allow an authenticated attacker to cause a denial of service or potentially execute arbitrary code due to an integer overflow in distribution list processing.
- CVE-2026-11375High
IBM MQ contains a stack buffer overflow when processing XA transaction identifiers. An authenticated attacker could exploit this to cause a denial of service or potentially execute arbitrary code.
- CVE-2026-10853High
IBM MQ improperly validates cluster command message lengths. An authenticated attacker with cluster access could cause a denial of service or potentially execute arbitrary code.
- CVE-2026-10575High
IBM MQ contains a heap buffer overflow when processing MQPUT operations with malformed distribution headers. An authenticated attacker could cause a denial of service or potentially escalate privileges.
- CVE-2026-10027High
IBM MQ contains a buffer overflow when processing malformed compressed data on channels configured with compression enabled. A remote attacker could cause a denial of service or execute arbitrary code.
