{"apiVersion":"1.0","identifier":"CVE-2026-72438","description":"In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix writes_pending and barrier reference leaks on discard failures raid10_make_request() acquires a writes_pending reference with md_write_start() before calling raid10_handle_discard(). Several failure paths in raid10_handle_discard() complete the bio and return without releasing the corresponding reference, causing md_write_end() to be skipped. Call md_write_end() before returning from these failure paths to keep writes_pending accounting balanced. Additionally, discard split allocation failures can occur after wait_barrier() succeeds. Those paths return without calling allow_barrier(), leaking the associated barrier reference. Release the barrier before returning from those paths.","publishedAt":"2026-08-15T06:22:17","lastModifiedAt":"2026-08-17T06:19:11","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72438","cvssScore":7.5,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","epssProbability":0.00359,"riskScore":0.77,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72438","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72438","en":"https://www.redsauce.net/en/cves/CVE-2026-72438","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72438","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72438","de":"https://www.redsauce.net/de/cves/CVE-2026-72438","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72438","el":"https://www.redsauce.net/el/cves/CVE-2026-72438"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72438"}}
