The userspace mappings are only\ncleaned up later in the mmap error path.\n\nFix it by explicitly flushing all mappings in our VMA on the error path.\n\nSee commit 79a61cc3fc04 (\"mm: avoid leaving partial pfn mappings around in\nerror case\").","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/16c507df509113c037cdc0ba642b9ab3389bd26c","https://git.kernel.org/stable/c/297f14fbb81895f4ccdb0ad25d196786d6461e00","https://git.kernel.org/stable/c/57f048c2d205b85e34282a9b0b0ae177e84c2f44","https://git.kernel.org/stable/c/8797b7712de704dc231f9e821d8eb3b9aeb3a032","https://git.kernel.org/stable/c/9b07fb464eb69a752406e78e62ab3a60bfa7b00d"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:57:56.913276502+00:00"},"epss":{"cve":"CVE-2024-53148","score":0.0025,"percentile":0.16407,"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).
