Environment

vSphere ESXi 8.0.3

Cause

ESXi hosts might fail with a purple diagnostic screen (PSOD) while processing SCSI commands from the guest OS.  An issue with the validation of SCSI commands from the guest OS at the virtual SCSI layer might cause an ESXi host to fail with a purple diagnostic screen.

Resolution

This issue is fixed in the latest version/build of ESXi 8.0 U3e (24674464). The fix adds enhanced command validation for SCSI commands at the virtual SCSI layer.  Update/Upgrade your ESXi host to this build.
