IBM i versions 7.3 through 7.6 contain a stack-based buffer overflow vulnerability (CWE-787) that can be triggered by a remote attacker with authentication. Exploitation could result in denial of service due to memory corruption on the stack. The CVSS 3.1 base score is 6.5, reflecting network attack vector, low attack complexity, required privileges, no user interaction, and impact limited to availability. No vendor advisory or patch information is provided at this time.

An authenticated remote attacker can cause a denial of service by exploiting a stack-based buffer overflow, leading to potential system crashes or service interruptions. There is no reported impact on confidentiality or integrity.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict remote authenticated access to trusted users and monitor for unusual system behavior related to service availability.
