CVE-2026-16013Public exploitNetwork attack vector

Remote service crash via unchecked symbolic length

Published Jul 17, 2026 · Updated Jul 17, 2026

Out-of-bounds read in CIPster commit 632336d414ef708a542377c1aa8d6fdb7c70a760 allows remote attackers to crash an ASan-enabled sample adapter. CipAppPath::deserialize_symbolic copies a segment-declared symbol length from the remaining BufReader without first confirming that enough bytes remain. The unconnected SendRRData path requires no authentication; reliable termination was demonstrated only with AddressSanitizer, and no write primitive was shown.
