CVE-2024-44987 is a use-after-free vulnerability in the Linux kernel IPv6 transmission function ip6_send_skb(). After ip6_local_out() returns, the routing object referenced by rt may no longer be valid, making subsequent dereferences unsafe without an RCU read lock. An observed failure occurred during raw IPv6 socket message handling, with KASAN detecting an eight-byte read from freed slab memory. The routing object was allocated through IPv6 blackhole-route handling and freed during RCU processing. The flaw can compromise kernel memory safety and system stability.
