The vulnerability is an out-of-bounds write in IBM i 7.6 that allows a remote attacker to corrupt memory and trigger a crash. The primary impact is a denial of service that may affect internal servers or services. This weakness corresponds to an imprecise boundary check in the DST/SST subsystem, resulting in an inability to maintain application integrity.

The affected product is IBM i version 7.6, including 7.6.0 and earlier 7.6 releases. The problem is limited to the mainframe OS component that handles DST/SST operations and is not present in newer supported releases.

The CVSS score of 7.5 indicates a high severity. The EPSS score is not available, so the exploitation probability is uncertain. The vulnerability is not listed in CISA KEV. The attack vector is inferred to be remote, leveraging the DST/SST protocol through open network interfaces, which modifies internal memory and causes a crash.
