{"id":"CVE-2024-46707","summary":"KVM: arm64: Make ICC_*SGI*_EL1 undef in the absence of a vGICv3","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: arm64: Make ICC_*SGI*_EL1 undef in the absence of a vGICv3\n\nOn a system with a GICv3, if a guest hasn't been configured with\nGICv3 and that the host is not capable of GICv2 emulation,\na write to any of the ICC_*SGI*_EL1 registers is trapped to EL2.\n\nWe therefore try to emulate the SGI access, only to hit a NULL\npointer as no private interrupt is allocated (no GIC, remember?).\n\nThe obvious fix is to give the guest what it deserves, in the\nshape of a UNDEF exception.","modified":"2026-04-02T12:19:29.742422Z","published":"2024-09-13T06:27:33.709Z","related":["SUSE-SU-2024:3551-1","SUSE-SU-2024:3553-1","SUSE-SU-2024:3559-1","SUSE-SU-2024:3561-1","SUSE-SU-2024:3564-1","SUSE-SU-2024:3566-1","SUSE-SU-2024:3569-1","SUSE-SU-2024:3587-1","SUSE-SU-2024:3591-1","SUSE-SU-2024:3592-1","SUSE-SU-2025:20073-1","SUSE-SU-2025:20077-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/46xxx/CVE-2024-46707.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/15818af2f7aa55eff375333cb7689df15d3f24ef"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2073132f6ed3079369e857a8deb33d11bdd983bc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3e6245ebe7ef341639e9a7e402b3ade8ad45a19f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/94d4fbad01b19ec5eab3d6b50aaec4f9db8b2d8d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/96b076e8ee5bc3a1126848c8add0f74bd30dc9d1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9d7629bec5c3f80bd0e3bf8103c06a2f7046bd92"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/10/msg00003.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/46xxx/CVE-2024-46707.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-46707"},{"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":"15818af2f7aa55eff375333cb7689df15d3f24ef"},{"fixed":"96b076e8ee5bc3a1126848c8add0f74bd30dc9d1"},{"fixed":"94d4fbad01b19ec5eab3d6b50aaec4f9db8b2d8d"},{"fixed":"9d7629bec5c3f80bd0e3bf8103c06a2f7046bd92"},{"fixed":"2073132f6ed3079369e857a8deb33d11bdd983bc"},{"fixed":"3e6245ebe7ef341639e9a7e402b3ade8ad45a19f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-46707.json"}}],"schema_version":"1.7.5"}
