Multiple security vulnerabilities were identified in the Linux kernel real-time variant affecting ARM64 architecture, Cryptographic API, Netfilter, and network traffic control subsystems. These flaws could potentially allow an attacker to compromise the system. The issues are addressed in the linux-image-5.15.0-1103-realtime package version 5.15.0-1103.112 and later. Users must update and reboot their systems, and recompile third-party kernel modules due to an ABI change.
