{"id":"CVE-2026-64105","summary":"KVM: arm64: vgic: Free private_irqs when init fails after allocation","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: arm64: vgic: Free private_irqs when init fails after allocation\n\nCompanion to commit 250f25367b58 (\"KVM: arm64: Tear down vGIC on\nfailed vCPU creation\"), which added the missing kvm_vgic_vcpu_destroy()\ncall to the kvm_share_hyp() failure path in kvm_arch_vcpu_create(). The\nkvm_vgic_vcpu_init() failure path immediately above it has the same\nshape and still needs the same cleanup.\n\nCall kvm_vgic_vcpu_destroy() when kvm_vgic_vcpu_init() fails so private\nIRQs allocated before a redistributor iodev registration failure are\nreleased before the failed vCPU is freed.","modified":"2026-07-21T03:47:53.133862956Z","published":"2026-07-19T15:40:08.605Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64105.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/173fb86e5519dbe7aabed1f5fa7456152a4a2e38"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7023900b4988fb6f4a59d304d878003ff562e98d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e690caa54a6139d98495ac69626807623520babd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f19c354dbd457759dfcf1195ab4bdba2bb568323"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64105.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64105"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"03b3d00a70b55857439511c1b558ca00a99f4126"},{"fixed":"173fb86e5519dbe7aabed1f5fa7456152a4a2e38"},{"fixed":"7023900b4988fb6f4a59d304d878003ff562e98d"},{"fixed":"e690caa54a6139d98495ac69626807623520babd"},{"fixed":"f19c354dbd457759dfcf1195ab4bdba2bb568323"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64105.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.10.0"},{"fixed":"6.12.92"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.34"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.11"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64105.json"}}],"schema_version":"1.7.5"}
