This release updates the Linux kernel and NVIDIA GPU driver to address security vulnerabilities and maintain driver support. It also fixes Fibre Channel crashes on Enterprise systems, an NFS server hang, false drive self-test alerts, deduplication table pruning errors, and directory services configuration changes.

1. The Linux kernel was updated from v6.12.95 to v6.12.99, the latest 6.12 LTS release, pulling in fixes for more than 250 upstream CVEs !!!
2. This release also moves the NVIDIA GPU driver to the 580 branch (v580.173.02)

Beyond the kernel and GPU driver, this release also fixes:

• Crashes when Fibre Channel target mode starts or stops on Enterprise systems
• An NFS server hang that could stop expiring clients after a brief network interruption — bad enough to require a reboot to clear
• False drive self-test failure alerts caused by TrueNAS reading the wrong SMART result
• Deduplication table (DDT) pruning errors that could misjudge entry age or overflow counters on very large tables
• A stuck Save button that blocked directory services configuration changes after upgrading from 25.04
• The ability to change the ALUA setting on Enterprise HA systems even when the standby controller is unreachable
• Failover speed on Enterprise HA systems, by moving a remote disk scan out of the critical failover path
• Audit entry parsing that could crash and restart the audit handler
