Multiple security vulnerabilities were discovered in the Linux kernel affecting the Cryptographic API, Netfilter, and Network traffic control subsystems. These flaws could potentially allow an attacker to compromise the system. The issues affect various versions of the linux-realtime kernel and have been addressed in updated package releases. Users must update and reboot their systems to apply the fixes. Due to an ABI change, recompilation and reinstallation of third-party kernel modules are required after the update.
