When deserializing CompactHashMap, CompactHashSet, or MapMakerInternalMap instances, Guava eagerly allocates an array based on a caller-specified size parameter without throttling, permitting memory exhaustion from crafted serialization streams.","state":0,"publishedAt":"2026-10-09T15:07:16.13+00:00","modifiedAt":"2026-10-09T18:09:50.1+00:00","affected":[{"ecosystem":"Vendor product","name":"Guava","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Google\",\n                    \"product\": \"Guava\",\n                    \"repo\": \"https://github.com/google/guava\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"4.0\",\n                            \"lessThan\": \"33.7.2\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.2,"severity":"HIGH"}],"references":["https://github.com/google/guava/security/advisories/GHSA-xxph-c9ww-hj94","https://github.com/google/guava/commit/b931fe9d6d5cf00bc55714ad3308d086f71850fe","https://github.com/google/guava/releases/tag/v33.7.2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102554","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102554","identifiers":["CVE-2026-102554"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
