A flaw was found in the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation. A race condition exists in the sctp_free_addr_wq() function during the cleanup of network address work queues. This allows a timer handler to access memory that has already been freed, leading to a use-after-free vulnerability. Such a vulnerability can cause system instability, including crashes, and potentially lead to denial of service.
