{"apiVersion":"1.0","identifier":"CVE-2026-74273","description":"In the Linux kernel, the following vulnerability has been resolved: cxl/region: Block region delete during region creation Expand the range lock, rename it -regions_lock-, to disable region deletion in the critical period between construct_region() and attach_target(), as well as the period between device_add() and registering the remove actions. Otherwise, userspace can confuse the kernel. It can violate the assumption the region stays registered through the completion of cxl_add_to_region(). It can violate the assumption that devm_add_action_or_reset() is working with a live -struct cxl_region-. It is ok for the region to disappear outside of those windows as that mirrors device hotplug flows where the proper locks are held.","publishedAt":"2026-08-15T06:22:26","lastModifiedAt":"2026-08-17T06:19:21","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74273","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00155,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74273","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74273","en":"https://www.redsauce.net/en/cves/CVE-2026-74273","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74273","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74273","de":"https://www.redsauce.net/de/cves/CVE-2026-74273","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74273","el":"https://www.redsauce.net/el/cves/CVE-2026-74273"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74273"}}
