Local code execution via out-of-bounds write
Published Aug 13, 2026 · Updated Aug 13, 2026
Out-of-bounds write in JSSE on IBM's integrated operating system 7.3 through 7.6 allows local users to execute arbitrary code. IBM identifies JSSE as the affected component but has not disclosed the code locus, buffer, or operation that writes beyond allocated bounds. A low-privileged local account is required, and successful exploitation runs attacker-controlled code in the affected system security context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=7.3
- Affected versionversion=7.4
- Affected versionversion=7.5
- Affected versionversion=7.6
