Multiple security vulnerabilities were discovered in the Linux kernel's real-time variant, specifically affecting the network traffic control subsystem. These flaws could potentially allow an attacker to compromise the system. A patch addressing these issues is available in version 6.8.1-1026.27 of the linux-realtime kernel. Users must update to this version and reboot their systems. Due to an ABI change, recompilation and reinstallation of third-party kernel modules are required after the update.
