The issue exists in the RUNVM instruction logic (VmState::run_child_vm), which is responsible for initializing child virtual machines. The operation moves critical resources (specifically libraries and log) from the parent state to a new child state in a non-atomic manner. If an Out-of-Gas (OOG) exception occurs after resources are moved but before the state transition is finalized, the parent VM retains a corrupted state where these resources are emptied/invalid. Because RUNVM supports gas isolation, the parent VM continues execution with this corrupted state, leading to unexpected behavior or denial of service within the contract's context.","publishedAt":"2026-02-13T00:00:00.000Z","updatedAt":"2026-02-17T15:15:36.481Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"CISA-ADP"},"assigner":"mitre","products":["n/a n/a"],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://github.com/ton-blockchain/ton/commit/1835d84602bbaaa1593270d7ab3bb0b499920416","https://github.com/ton-blockchain/ton/releases/tag/v2025.04#:~:text=Arayz%2C%20Robinlzw%2C%20%40wy666444%20%40Lucian-code233","https://mp.weixin.qq.com/s/ZD35baKUikefFdtNHZIC9g","https://gist.github.com/Lucian-code233/beab9d14683ed2bdf5543be430b91c70"],"weaknesses":["CWE-1321"],"ingestedAt":"2026-10-29T20:10:04.440Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/70xxx/CVE-2025-70956.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-70956","state":"PUBLISHED","datePublished":"2026-02-13T00:00:00.000Z","dateUpdated":"2026-02-17T15:15:36.481Z","assignerShortName":"mitre","assignerOrgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","dateReserved":"2026-01-09T00:00:00.000Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"A State Pollution vulnerability was discovered in the TON Virtual Machine (TVM) before v2025.04.
