If those offsets point beyond the end of the file this could lead to Virtual Machine Monitors using the `linux-loader` crate entering an infinite loop if the ELF header of the kernel they are loading was modified in a malicious manner. This issue has been addressed in 0.8.1. The issue can be mitigated by ensuring that only trusted kernel images are loaded or by verifying that the headers do not point beyond the end of the file.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-119","CWE-125"],"references":["https://github.com/rust-vmm/linux-loader/pull/125","https://github.com/rust-vmm/linux-loader/security/advisories/GHSA-52h2-m2cf-9jh6","https://github.com/rust-vmm/linux-loader/pull/125","https://github.com/rust-vmm/linux-loader/security/advisories/GHSA-52h2-m2cf-9jh6"],"products":["linux-loader_project:linux-loader"],"source":"nvd","synced_at":"2026-10-19T21:37:28.463369388+00:00"},"epss":{"cve":"CVE-2022-23523","score":0.00216,"percentile":0.12141,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-52h2-m2cf-9jh6","url":"https://osv.dev/vulnerability/GHSA-52h2-m2cf-9jh6","summary":"linux-loader reading beyond EOF could lead to infinite loop","modified":"2023-11-08T04:08:20.739426Z","packages":[{"ecosystem":"crates.io","name":"linux-loader","purl":"pkg:cargo/linux-loader","ranges":["<0.8.1"],"fixed":["0.8.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
