KI-Zusammenfassung:
  Linux kernel 6.6.159 (longterm) was a maintenance release focused primarily on networking stability and security fixes. The most notable security-related changes included freeing inet_opt and ireq_opt after an RCU grace period in IPv4 to prevent use-after-free vulnerabilities, validating checksum_start before completing checksum calculations in IPv4 to avoid potential memory corruption or crashes, and fixing a regression in netfilter's nfnetlink_queue subsystem that had broken SCTP traffic handling. These changes primarily targeted the IPv4 networking stack and netfilter subsystem, addressing both memory safety issues and functional regressions. Overall, this release emphasized hardening core networking code against race conditions and malformed packet handling while restoring proper SCTP protocol support through netfilter queues.

Alle Änderungen (3):
  - ipv4: free inet_opt and ireq_opt after an RCU grace period
  - ipv4: validate checksum_start before completing checksum
  - netfilter: nfnetlink_queue: unbreak SCTP traffic
