CVE-2026-11375

Name of the Vulnerable Software and Affected Versions IBM MQ (affected versions not specified)

Description An authenticated attacker can cause a denial of service or potentially execute arbitrary code. This is possible due to a stack buffer overflow, which occurs when the system processes XA transaction identifiers. A stack buffer overflow is a condition where a program writes more data to a buffer located on the stack than the buffer is allocated to hold, potentially overwriting adjacent memory.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
