{"apiVersion":"1.0","identifier":"CVE-2026-74725","description":"In the Linux kernel, the following vulnerability has been resolved: enic: fix tx_hang_reset use-after-free on device removal enic_remove() cancels the reset and change_mtu_work items but does not cancel tx_hang_reset. A TX timeout that fires while the device is being removed can schedule enic_tx_hang_reset() so that it runs after free_netdev(), resulting in a use-after-free. cancel_work_sync() alone is not sufficient here: the still-live watchdog and notify paths can re-schedule these work items in the window between the cancel and unregister_netdev(). Use disable_work_sync(), which cancels the work and blocks any subsequent schedule_work() from requeuing it, and apply it to the reset and change_mtu_work items as well so the same requeue race is closed for all teardown work.","publishedAt":"2026-08-22T16:16:47","lastModifiedAt":"2026-08-25T06:18:58","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74725","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00125,"riskScore":0.79,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74725","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74725","en":"https://www.redsauce.net/en/cves/CVE-2026-74725","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74725","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74725","de":"https://www.redsauce.net/de/cves/CVE-2026-74725","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74725","el":"https://www.redsauce.net/el/cves/CVE-2026-74725"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74725"}}
