For PI metadata this is\nlimited to the app tag that isn't used by kernel generated metadata,\nbut for non-PI metadata the entire buffer leaks kernel memory.\n\nFix this by adding the __GFP_ZERO flag to allocations for writes.","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-401"],"references":["https://git.kernel.org/stable/c/129f95948a96105c1fad8e612c9097763e88ac5f","https://git.kernel.org/stable/c/23a19655fb56f241e592041156dfb1c6d04da644","https://git.kernel.org/stable/c/3fd11fe4f20756b4c0847f755a64cd96f8c6a005","https://git.kernel.org/stable/c/899ee2c3829c5ac14bfc7d3c4a5846c0b709b78f","https://git.kernel.org/stable/c/9f4af4cf08f9a0329ade3d938f55d2220c40d0a6"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:54:16.205165117+00:00"},"epss":{"cve":"CVE-2024-43854","score":0.00234,"percentile":0.14369,"date":"2026-10-31"},"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).
