{"apiVersion":"1.0","identifier":"CVE-2026-99045","description":"In the Linux kernel, the following vulnerability has been resolved: ibmveth: h_free logical LAN on open-fail after register ibmveth_open() registers the logical LAN, then allocates the RX buffer pools. A pool failure jumps to out_free_buffer_pools without h_free_logical_lan(), so PHYP still owns the buffer-list page when it is unmapped. request_irq() failure already issued the hypercall before taking the same label. Move that h_free to the shared post-register unwind so both paths deregister before the buffer list is unmapped.","publishedAt":"2026-10-23T13:17:27","lastModifiedAt":"2026-10-30T13:21:41","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-99045","cvssScore":null,"cvssVector":null,"epssProbability":0.00185,"riskScore":null,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-99045","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-99045","en":"https://www.redsauce.net/en/cves/CVE-2026-99045","fr":"https://www.redsauce.net/fr/cves/CVE-2026-99045","pt":"https://www.redsauce.net/pt/cves/CVE-2026-99045","de":"https://www.redsauce.net/de/cves/CVE-2026-99045","sk":"https://www.redsauce.net/sk/cves/CVE-2026-99045","el":"https://www.redsauce.net/el/cves/CVE-2026-99045"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-99045"}}
