Veeam Software Appliance VMs running on certain AMD EPYC processors intermittently fail to boot after jitterentropy health test failure in FIPS mode.

Veeam has warned that its Software Appliance virtual machines, pre-configured Linux-based VMs for running Veeam Backup & Replication, will fail to boot with a kernel panic on certain AMD EPYC processors including 7262, 7302, and 7F72. The issue stems from the Linux kernel's jitterentropy health test failing in FIPS mode during early boot for version 13.1 and later. Users are advised to redeploy the appliance to a host with a different processor or disable automatic updates and install them manually. Veeam also noted that some products are affected by a critical Linux kernel vulnerability (CVE-2026-98432) in the IPv4 TCP networking code.

Key facts
  • Fails on AMD EPYC 7262, 7302, and 7F72 processors
  • Known issue in Linux kernel used by the appliance
  • Power off and on the VM after kernel panic to recover
  • Affects version 13.1 and later of Software Appliance
