Authenticated process termination via PASE buffer overflow
Published Sep 14, 2026 · Updated Sep 14, 2026
A buffer overflow in a PASE process in IBM i 7.3 through 7.6 allows local users to terminate their own process. IBM has not disclosed the affected PASE routine or the unchecked operation that overflows its buffer. Exploitation requires authenticated access, and the documented consequence is limited to termination of the attacker's process.
