{"apiVersion":"1.0","identifier":"CVE-2026-72042","description":"In the Linux kernel, the following vulnerability has been resolved: ipmi: Fix user refcount underflow in event delivery ipmi_alloc_recv_msg(user) takes the temporary user reference owned by the receive message, and ipmi_free_recv_msg() drops it again. If event delivery fails after allocating receive messages for earlier users, handle_read_event_rsp() rolls those messages back with ipmi_free_recv_msg(). That rollback path still drops user->refcount explicitly after freeing each message. The extra put can free a user that remains linked on intf->users, so later event delivery may dereference a freed user or trip refcount_t-s addition-on-zero warning when ipmi_alloc_recv_msg() tries to acquire another reference. Remove the stale explicit put and the now-dead user assignment. Keep the list_del() and ipmi_free_recv_msg() calls; they are the required rollback operations.","publishedAt":"2026-08-15T06:21:13","lastModifiedAt":"2026-08-17T06:18:02","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72042","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00162,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72042","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72042","en":"https://www.redsauce.net/en/cves/CVE-2026-72042","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72042","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72042","de":"https://www.redsauce.net/de/cves/CVE-2026-72042","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72042","el":"https://www.redsauce.net/el/cves/CVE-2026-72042"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72042"}}
