Unauthenticated information disclosure via out-of-bounds read
Published Aug 13, 2026 · Updated Aug 13, 2026
Out-of-bounds read in NetServer on IBM operating system releases 7.3 through 7.6 allows remote attackers to obtain sensitive information. IBM has not disclosed the affected request handler, input field, or operation that reads beyond the intended buffer. The path requires neither authentication nor user interaction, and the documented consequence is sensitive-data disclosure rather than attacker-controlled modification.

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.
