Ubuntu USN-8668-2 Fixes Linux kernel (Raspberry Pi) Vulnerabilities
Ubuntu 22.04 Raspberry Pi systems need the linux-raspi update matched to their package, not hardware branding alone. Arrange remote recovery access, check third-party modules, and coordinate the required reboot with the device owner.
Ubuntu USN-8726-3 Fixes Linux kernel (IBM) Vulnerabilities
The Ubuntu 26.04 IBM kernel update is distinct from the Ubuntu 24.04 IBM package. Match the running linux-ibm release, check module compatibility and recovery access, and schedule the required reboot with workload owners.
