Multiple security vulnerabilities were discovered in the Linux kernel for Raspberry Pi, Raspberry Pi Real-time, and Xilinx systems. These include a branch predictor isolation flaw known as VMSCAPE (CVE-2025-40300) that could allow an attacker in a guest VM to expose sensitive information from the host OS. Additional flaws affect the HSI, Bluetooth, and Timer subsystems. Updates correcting these issues have been released and require a system reboot and recompilation of third-party kernel modules due to ABI changes.
