So, accessing them requires mutual exclusion using\nthe reader/writer semaphore \"nilfs->ns_sem\".\n\nSome sysfs attribute show methods read this superblock buffer without the\nnecessary mutual exclusion, which can cause problems with pointer\ndereferencing and memory access, so fix it.","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/157c0d94b4c40887329418c70ef4edd1a8d6b4ed","https://git.kernel.org/stable/c/19cfeba0e4b8eda51484fcf8cf7d150418e1d880","https://git.kernel.org/stable/c/683408258917541bdb294cd717c210a04381931e","https://git.kernel.org/stable/c/8c6e43b3d5f109cf9c61bc188fcc8175404e924f","https://git.kernel.org/stable/c/962562d4c70c5cdeb4e955d63ff2017c4eca1aad"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:54:38.012257375+00:00"},"epss":{"cve":"CVE-2024-46780","score":0.0024,"percentile":0.1509,"date":"2026-11-01"},"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).
