Citrix has released patches addressing a critical memory overflow vulnerability affecting NetScaler ADC and NetScaler Gateway. Tracked as CVE-2026-107406, the flaw can lead to remote code execution or denial-of-service under specific configuration conditions, according to Citrix.
The vulnerability is particularly relevant to SAML deployments, where exploitation could potentially enable RCE. Citrix has not disclosed further technical details beyond the memory overflow nature of the flaw and the conditions required for exploitation.
Affected products:

Administrators running these products, especially in SAML configurations, should review Citrix's advisory and apply the available patches as soon as possible. Given the severity of potential RCE, prioritising this update is strongly recommended.
