CVE-2024-35969 is a race condition in the Linux kernel IPv6 subsystem between ipv6_get_ifaddr() and ipv6_del_addr(). While ipv6_get_ifaddr() traverses the IPv6 address list under RCU protection, it can obtain an address object concurrently removed by ipv6_del_addr(). RCU prevents immediate reclamation but does not ensure that the removed object's state remains valid. The deletion path can reduce the object's reference count to zero and queue it for RCU reclamation before the lookup path increments the reference count. The lookup may consequently return an object that is freed after the RCU read-side critical section, resulting in a use-after-free condition. The fix uses a safe reference-acquisition operation that refuses to increment a zero reference count.
