{"apiVersion":"1.0","identifier":"CVE-2026-72289","description":"In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic: Check the interrupt is still ours before migrating it vgic_prune_ap_list() drops both ap_list_lock and irq_lock while migrating an interrupt to another vCPU. After reacquiring the locks it only checks that the affinity is unchanged (target_vcpu == vgic_target_oracle(irq)) before moving the interrupt, which assumes that an interrupt whose affinity is preserved is still queued on this vCPU-s ap_list. That assumption no longer holds if the interrupt is taken off the ap_list while the locks are dropped. vgic_flush_pending_lpis() removes the interrupt from the list and sets irq->vcpu to NULL, but leaves enabled/pending/target_vcpu untouched. As the interrupt is still enabled and pending, vgic_target_oracle() returns the same target_vcpu, so the affinity check passes and list_del() is run a second time on an entry that has already been removed. Also check that the interrupt is still assigned to this vCPU (irq->vcpu == vcpu) before moving it.","publishedAt":"2026-08-15T06:22:00","lastModifiedAt":"2026-08-17T06:18:31","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72289","cvssScore":9.3,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.00185,"riskScore":0.95,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72289","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72289","en":"https://www.redsauce.net/en/cves/CVE-2026-72289","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72289","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72289","de":"https://www.redsauce.net/de/cves/CVE-2026-72289","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72289","el":"https://www.redsauce.net/el/cves/CVE-2026-72289"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72289"}}
