{"apiVersion":"1.0","identifier":"CVE-2026-72218","description":"In the Linux kernel, the following vulnerability has been resolved: lockd: Plug nlm_file refcount leak on cached nlm_do_fopen() failure The cached-file path in nlm_lookup_file() reaches the found: label unconditionally, even when nlm_do_fopen() fails. At that label *result and file->f_count are updated before the error is returned. The wrappers nlm3svc_lookup_file() and nlm4svc_lookup_file() then bail out of their switch without copying *result back to their caller, so the proc handler-s local nlm_file pointer remains NULL and the cleanup path skips nlm_release_file(). The f_count increment is never released, and nlm_traverse_files() can no longer reap the file because its refcount never returns to zero between requests. Short-circuit the cached path so neither *result nor f_count is touched when nlm_do_fopen() fails on a hashed nlm_file.","publishedAt":"2026-08-15T06:21:40","lastModifiedAt":"2026-08-17T06:18:22","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72218","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00216,"riskScore":0,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72218","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72218","en":"https://www.redsauce.net/en/cves/CVE-2026-72218","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72218","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72218","de":"https://www.redsauce.net/de/cves/CVE-2026-72218","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72218","el":"https://www.redsauce.net/el/cves/CVE-2026-72218"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72218"}}
