{"apiVersion":"1.0","identifier":"CVE-2026-74316","description":"In the Linux kernel, the following vulnerability has been resolved: NFSD: Handle layout stid in nfsd4_drop_revoked_stid() nfsd4_drop_revoked_stid() has no SC_TYPE_LAYOUT case, so when a client sends FREE_STATEID for an admin-revoked layout stid, the default branch releases cl_lock and returns without unhashing or releasing the stid. The stid remains in the IDR and on the per-client list until the client is destroyed. Remove the layout stid from the per-client list and call nfs4_put_stid() to drop the creation reference. When the refcount reaches zero, nfsd4_free_layout_stateid() handles the remaining cleanup: cancelling the fence worker, removing from the per-file list, and freeing the slab object.","publishedAt":"2026-08-15T06:22:31","lastModifiedAt":"2026-08-17T06:19:25","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74316","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00441,"riskScore":0.78,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74316","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74316","en":"https://www.redsauce.net/en/cves/CVE-2026-74316","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74316","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74316","de":"https://www.redsauce.net/de/cves/CVE-2026-74316","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74316","el":"https://www.redsauce.net/el/cves/CVE-2026-74316"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74316"}}
