{"id":"CVE-2024-26691","summary":"KVM: arm64: Fix circular locking dependency","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: arm64: Fix circular locking dependency\n\nThe rule inside kvm enforces that the vcpu-\u003emutex is taken *inside*\nkvm-\u003elock. The rule is violated by the pkvm_create_hyp_vm() which acquires\nthe kvm-\u003elock while already holding the vcpu-\u003emutex lock from\nkvm_vcpu_ioctl(). Avoid the circular locking dependency altogether by\nprotecting the hyp vm handle with the config_lock, much like we already\ndo for other forms of VM-scoped data.","modified":"2026-04-02T10:05:33.650869Z","published":"2024-04-03T14:54:52.518Z","related":["SUSE-SU-2024:2802-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2973-1","SUSE-SU-2024:3194-1","SUSE-SU-2024:3383-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26691.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/10c02aad111df02088d1a81792a709f6a7eca6cc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3ab1c40a1e915e350d9181a4603af393141970cc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3d16cebf01127f459dcfeb79ed77bd68b124c228"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26691.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-26691"},{"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":"6211753fdfd05af9e08f54c8d0ba3ee516034878"},{"fixed":"3d16cebf01127f459dcfeb79ed77bd68b124c228"},{"fixed":"3ab1c40a1e915e350d9181a4603af393141970cc"},{"fixed":"10c02aad111df02088d1a81792a709f6a7eca6cc"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-26691.json"}}],"schema_version":"1.7.5"}
