However the\nnext allocation from the same bitmap will notice the bitmap buffer is\nalready loaded and tries to allocate from the bitmap with mixed results\n(depending on the exact nature of the bitmap corruption). Fix the\nproblem by using BH_verified bit to indicate whether the bitmap is valid\nor not.","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":[],"references":["https://git.kernel.org/stable/c/2199e157a465aaf98294d3932797ecd7fce942d5","https://git.kernel.org/stable/c/271cab2ca00652bc984e269cf1208699a1e09cdd","https://git.kernel.org/stable/c/57053b3bcf3403b80db6f65aba284d7dfe7326af","https://git.kernel.org/stable/c/6a43e3c210df6c5f00570f4be49a897677dbcb64","https://git.kernel.org/stable/c/8ca170c39eca7cad6e0cfeb24e351d8f8eddcd65"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2024-42306","score":0.00246,"percentile":0.15664,"date":"2026-10-26"},"kev":null,"osv":[],"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).
