CVE-2026-88776 is a memory-overflow vulnerability in Citrix NetScaler ADC and Citrix NetScaler Gateway. It affects deployments that have a load-balancing virtual server configured for the Oracle protocol. Processing of network input in the affected configuration can trigger memory corruption, resulting in unpredictable or erroneous appliance behavior or denial of service. Affected releases include ADC and Gateway versions before 14.1-73.37 or 13.1-64.23; ADC 14.1 FIPS before 14.1-73.37 FIPS; and ADC 13.1 FIPS/NDcPP before 13.1-37.279.
