CVE-2026-17262

IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to execute arbitrary code due to a stack-based buffer overflow.

IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to escalate privileges due to improper authorization in the handling of high-authority threads.

IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to execute arbitrary code due to an out-of-bounds write.

IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to execute arbitrary code due to an uncontrolled search path element.

IBM i versions 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to bypass security restrictions and access internal network services due to improper validation of FTP PORT and EPRT commands.

IBM i versions 7.6, 7.5, 7.4, and 7.3 could allow a denial of service as a result of a buffer overflow in a PASE process. An authenticated attacker could leverage this to terminate their own process.

IBM i versions 7.6, 7.5, 7.4, and 7.3 contain a buffer overflow in a PASE process that can lead to denial of service. An authenticated attacker could leverage this to terminate their own process.

IBM i versions 7.6, 7.5, 7.4, and 7.3 could allow a local attacker to obtain ownership of arbitrary file system objects due to a time-of-check to time-of-use (TOCTOU) race condition.

IBM i versions 7.6, 7.5, 7.4, and 7.3 may allow a remote attacker to obtain sensitive information due to improper validation of the WebSocket origin.

IBM i versions 7.6, 7.5, 7.4, and 7.3 may allow a remote unauthenticated attacker to gain access to sensitive information through session IP binding bypass in Navigator for i.
