{"apiVersion":"1.0","identifier":"CVE-2026-74605","description":"In the Linux kernel, the following vulnerability has been resolved: eventfs: Use children field for rcu head and add memory barriers When an eventfs inode is freed, it sets ei->is_freed and then uses its ei->list to add it to the srcu link list as the list field is a union with the rcu list head. As the ei->list is used to iterate over an SRCU protected list without taking the eventfs_mutex, there-s nothing stopping the iteration over that list to see the ei->rcu instead of the ei->list and it will read a corrupt target. To fix this, change the union of the rcu list head with the children list. On freeing the eventfs inode, set the is_free and execute a smp_wmb() before adding the eventfs inode to the SRCU list. On iteration of the ei->children list, at the start, execute a smp_rmb() and then read the is_freed of the ei to see if the children list is still valid. If is_freed is set, then the ei_child read is not valid and the loop should exit immediately.","publishedAt":"2026-08-22T16:16:32","lastModifiedAt":"2026-08-25T06:18:36","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74605","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.0012,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74605","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74605","en":"https://www.redsauce.net/en/cves/CVE-2026-74605","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74605","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74605","de":"https://www.redsauce.net/de/cves/CVE-2026-74605","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74605","el":"https://www.redsauce.net/el/cves/CVE-2026-74605"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74605"}}
