An entry length near U32_MAX wraps it to a small\nvalue, bypasses the bounds check, and is then used to index the entry,\nreading far past the directory part -- an out-of-bounds read that oopses\nthe kernel.\n\nCompute the size as a u64 so it cannot truncate; the bounds check then\nrejects the entry. The trailer is supplied by the userspace client.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":[],"references":["https://git.kernel.org/stable/c/07c05601a9a8e5d4481b2a4a16dc0e3c5bc63ad9","https://git.kernel.org/stable/c/1679780f482feeb82acb5995587d4fb1d1fe82fd","https://git.kernel.org/stable/c/18227a6bc98bd0ba96ed3ce9d5b28776a5a28dfc","https://git.kernel.org/stable/c/36723b28e3293047f087f4501f1ef4ead418dd84","https://git.kernel.org/stable/c/82fc886e244c76fadf05ef1958aaf8815478ccde"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72033","score":0.00793,"percentile":0.56352,"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).
