Any remote host that can route an IPv4/IPv6 SCTP packet to the target reaches it.\nAC:L - The attacker fully controls the packet: a single chunk followed by 1\u20133 trailing bytes with a computable CRC32c checksum deterministically drives the loop one iteration past the last complete chunk. No race, no memory-layout dependency, no victim state required.\nPR:N - `__sctp_rcv_lookup_endpoint()` falls back to the per-netns `ctl_sock` endpoint, so out-of-the-blue packets are processed in `SCTP_STATE_CLOSED` even with no listening SCTP socket and no association. The attacker needs no credentials or prior handshake.\nUI:N - The bug triggers in softirq packet-receive context on arrival of the malformed packet. No local user has to open, mount, or configure anything.\nS:U - The out-of-bounds read and any resulting fault stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:L - The chunk-length field is read up to 2 bytes past `skb_tail_pointer()` into uninitialized kernel memory, a genuine read outside the intended buffer. It is strictly bounded to those 2 bytes and both resulting branches converge on `sctp_sf_violation_chunklen()`, so the value is not echoed back \u2014 limited rather than arbitrary disclosure.\nI:N - The defect is purely a read; no kernel memory is written out of bounds and no attacker-influenced data alters kernel state beyond the standard ABORT response the packet would trigger anyway.\nA:H - The upstream commit describes the issue as a crash, and the syzbot KMSAN report is fatal on kernels with panic_on_warn, so an unauthenticated remote attacker can repeatedly panic an affected system by replaying the malformed packet."
