Versions 9.18 through 26.00 contain a heap out-of-bounds read in 7-Zip Ar handler BSD SYMDEF parser. A 4-byte heap out-of-bounds read exists in the Unix ar archive parser in 7-Zip. When parsing a BSD-style __.SYMDEF symbol table, the ParseLibSymbols function reads a 32-bit namesSize field via Get32 at a position that can equal the buffer size, reading 4 bytes past the end of the heap allocation. This reads uninitialized heap data under the default allocator. Version 26.01 patches the issue."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"mcmilk","product":"7-Zip","versions":[{"version":"\u003e= 9.34, \u003c 26.01","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-06-05T19:38:30.375424Z","id":"CVE-2026-48112","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-125"},{"lang":"en","value":"CWE-190"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:7-zip:7-zip:*:*:*:*:*:*:*:*","versionStartIncluding":"9.34","versionEndExcluding":"26.01","matchCriteriaId":"E06D6657-3843-4900-BF1C-5B524F7D649C"}]}]}],"references":[{"url":"https://securitylab.github.com/advisories/GHSL-2026-115_GHSL-2026-122_7-zip/","source":"security-advisories@github.com","tags":["Exploit","Patch","Third Party Advisory"]}]}}
