Multiple security vulnerabilities were discovered in the Linux kernel, specifically affecting the linux-raspi-realtime and linux-realtime kernels. These flaws impact subsystems including InfiniBand drivers, Netfilter, and network traffic control. An attacker could potentially exploit these issues to compromise the system. Fixes have been released in updated kernel versions, and users are advised to update and reboot their systems. Due to an ABI change, recompilation of third-party kernel modules is required after the update.
