From 30.0.0 to 36.0.8, 43.0.2, and 44.0.1, Wasmtime's allocation logic for a WebAssembly table contained checked arithmetic which panicked on overflow. This overflow is possible to trigger, and thus panic, when a table with an extremely large size is allocated. This is possible with the WebAssembly memory64 proposal where tables can have sizes in the 64-bit range as opposed to the previous 32-bit range which would not overflow. The panic happens when attempting to create a very large table, such as when instantiating a WebAssembly module or component. This vulnerability is fixed in 36.0.8, 43.0.2, and 44.0.1.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":5.9,"severity":null}],"references":["https://github.com/bytecodealliance/wasmtime/security/advisories/GHSA-p8xm-42r7-89xg"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-30304","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"May 14, 2026, 2:54:32 PM","dateUpdated":"Jul 28, 2026, 12:04:48 PM"},"relatedAdvisories":[{"id":"openSUSE-SU-2026:10802-1","title":"libtree-sitter0_26-0.26.8-3.1 on GA media","vulnerabilityIds":["CVE-2026-44216"]},{"id":"openSUSE-SU-2026:20863-1","title":"Security update for tree-sitter","vulnerabilityIds":["CVE-2026-44216"]},{"id":"RHSA-2026:45341","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","vulnerabilityIds":["CVE-2025-11233","CVE-2026-44216"]},{"id":"SUSE-SU-2026:22002-1","title":"Security update for tree-sitter","vulnerabilityIds":["CVE-2026-44216"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
