Multiple security vulnerabilities were identified in the Linux kernel for IBM cloud systems, specifically affecting the network traffic control subsystem. These flaws could potentially allow an attacker to compromise the system. The issues are addressed in the linux-ibm-6.8 kernel update version 6.8.0-1030.30~22.04.1. Users must update and reboot their systems, and recompile any third-party kernel modules due to an ABI change.
