      "scenario": "AV:N - The malformed media address is parsed straight out of a TIPC LINK_CONFIG discovery packet received on the UDP bearer socket (port 6118), which accepts routable unicast/replicast traffic from arbitrary sources with no peer-address check in tipc_udp_recv(). A remote host can therefore reach the vulnerable code with a single crafted UDP datagram.\nAC:L - One crafted packet with proto set to any value other than ETH_P_IP/ETH_P_IPV6 and msg_prevnode=0 deterministically reaches disc_dupl_alert() and the uninitialized-buffer read; there is no race, no memory-layout dependency, and no condition outside the attacker's control.\nPR:N - TIPC neighbor discovery is processed before any link is established and, with the default configuration (no CONFIG_TIPC_CRYPTO keys), involves no authentication whatsoever. The attacker needs no account or credentials on the target.\nUI:N - The victim node processes incoming discovery messages automatically in softirq context; no administrator or user action is required beyond having the UDP bearer already enabled.\nS:U - The out-of-bounds read and the leaked data both stay within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The %s conversion reads an uninitialized 60-byte stack buffer past its end until a NUL byte, and the harvested kernel stack contents are printed into the kernel log via pr_warn \u2014 an unbounded stack out-of-bounds read that can disclose kernel pointers and defeat KASLR.\nI:N - No out-of-bounds or attacker-controlled write occurs; every scnprintf() destination remains correctly length-bounded, so no kernel data is modified.\nA:H - The unbounded stack read can fault into the VMAP_STACK guard page and immediately panics KASAN/panic_on_warn kernels as a stack-out-of-bounds report, and the trigger is a non-ratelimited pr_warn that a remote attacker can drive repeatedly."
