{"id":"CVE-2026-43245","summary":"ntfs: -\u003ed_compare() must not block","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: -\u003ed_compare() must not block\n\n... so don't use __getname() there.  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.","modified":"2026-07-15T01:49:13.073393532Z","published":"2026-05-06T11:28:37.602Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43245.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/02ecc0978c459fd90bb24b2a946dd16d43e68fe5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/142c444a395f4d26055c8a4473e228bb86283f1e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1be7ca86ce1794d966fda5d82181bc978b150fbc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ca2a04e84af79596e5cd9cfe697d5122ec39c8ce"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fb4b1f969ba01fa1d4088467a02fc1e5f0806710"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43245.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43245"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"a3a956c78efaa202b1d75190136671cf6e87bfbe"},{"fixed":"02ecc0978c459fd90bb24b2a946dd16d43e68fe5"},{"fixed":"1be7ca86ce1794d966fda5d82181bc978b150fbc"},{"fixed":"142c444a395f4d26055c8a4473e228bb86283f1e"},{"fixed":"fb4b1f969ba01fa1d4088467a02fc1e5f0806710"},{"fixed":"ca2a04e84af79596e5cd9cfe697d5122ec39c8ce"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43245.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.141"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.91"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43245.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
