Switch it (and ntfs_d_hash(), while\nwe are at it) to kmalloc(PATH_MAX, GFP_NOWAIT).  Yes, ntfs_d_hash()\nalmost certainly can do with smaller allocations, but let ntfs folks\ndeal with that - keep the allocation size as-is for now.\n\nStop abusing names_cachep in ntfs, period - various uses of that thing\nin there have nothing to do with pathnames; just use k[mz]alloc() and\nbe done with that.  For now let's keep sizes as-in, but AFAICS none of\nthe users actually want PATH_MAX.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":[],"references":["https://git.kernel.org/stable/c/02ecc0978c459fd90bb24b2a946dd16d43e68fe5","https://git.kernel.org/stable/c/142c444a395f4d26055c8a4473e228bb86283f1e","https://git.kernel.org/stable/c/1be7ca86ce1794d966fda5d82181bc978b150fbc","https://git.kernel.org/stable/c/ca2a04e84af79596e5cd9cfe697d5122ec39c8ce","https://git.kernel.org/stable/c/fb4b1f969ba01fa1d4088467a02fc1e5f0806710"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-43245","score":0.00441,"percentile":0.38294,"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).
