The Cortex XSIAM release includes the following known issues:

Issue ID	Description
EXPANDR-10350	On threat details pages in the Threat Response Center, clicking on the Unassigned user in the Active Incidents by Assignee widget opens the Incidents page with an incorrect number of incidents. This issue impacts customers with the Attack Surface Management add-on module whose tenant was created before July 14, 2024.
EXPANDR-10351	On threat details pages in the Threat Response Center, the All Incidents for this Threat button, opens the Incidents page with an incorrect number of incidents. This issue impacts customers with the Attack Surface Management add-on module whose tenant was created before July 14, 2024.
CPATR-25409	In some cases, when the XDR Collectors is installed on a Linux platform, the XDR Collectors fails to register due to an incorrect operating system version. As a workaround, remove the `agilitytools` application and restart XDR Collectors.
CPATR-20105	When performing a XDR Collectors installation or upgrade in Linux using a shell installer, the `/tmp` folder cannot be marked as `noexec`. Otherwise, the installation or upgrade fails. As a workaround, before the installation or upgrade, use the following command: mount -o remount,exec /tmp Note The `deb` and `rpm` installations work fine without any problems.
CRTX-67376	Users with dataset role-based access control (RBAC) permissions can view already-created correlation rules using the data model on the Correlation Rules page, but can’t create or edit them. When users view the alerts for those rules, they can see neither the relevant pivots, nor the rule itself.
CRTX-57553	When setting up the Broker VM on Google Cloud Platform (GCP) and a GCP image is imported using the G Cloud CLI, the following command fails. `gcloud compute images import <VMDK image> --os=ubuntu-1804 --source-file="gs://<image path>" --network=<network_name> --subnet=<subnet_name> --zone=<region> --async` Until this is resolved as a workaround, use the following command. `gcloud compute images import <VMDK image> --data-disk --source-file="gs://<image path>" --network=<network_name> --subnet=<subnet_name> --zone=<region> --async`
CRTX-41336	A Database Collector applet on a broker VM that is deployed in a Cortex XDR FedRAMP environment cannot connect to MySQL and MSSQL.
XDR-55313	When exporting Restriction type profile with custom indicator rules and then importing those back, the rules are no longer available.
N/A	Currently, the Cortex XSIAM product URL contains the `xdr` product name as opposed to `xsiam`.
CPATR-15036	Cortex XSIAM only supports stitching login Windows Event Logs into stories for a Windows 8.1 or later machine.
XDR-30122	When your XQL query includes a filter with a result that is an exponential number, the filter can sometimes not work as expected, including not returning any results.
XDR-29691	Cortex XSIAM calculates CVEs for applications according to the application version, and not according to application build numbers.
XDR-21780	Backwards scan is not supported when generating a BIOC from the Native Search.
CPATR-10766	After a Microsoft Windows patch (KB) is uninstalled from the endpoint, the Cortex XDR agent continues to report this KB to Cortex XDR. As a result, the CVEs list for the endpoint in Vulnerability Management cannot be updated to include the CVEs addressed by the uninstalled KB.
