The handle_mmio()\nfunction checks if the #VE exception occurred in the kernel and rejects\nthe operation if it did not.\n\nHowever, userspace can deceive the kernel into performing MMIO on its\nbehalf. For example, if userspace can point a syscall to an MMIO address,\nsyscall does get_user() or put_user() on it, triggering MMIO #VE. The\nkernel will treat the #VE as in-kernel MMIO.\n\nEnsure that the target MMIO address is within the kernel before decoding\ninstruction."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/x86/coco/tdx/tdx.c"],"versions":[{"version":"31d58c4e557d46fa7f8557714250fb6f89c941ae","lessThan":"25703a3c980e21548774eea8c8a87a75c5c8f58c","status":"affected","versionType":"git"},{"version":"31d58c4e557d46fa7f8557714250fb6f89c941ae","lessThan":"4c0c5dcb5471de5fc8f0a1c4980e5815339e1cee","status":"affected","versionType":"git"},{"version":"31d58c4e557d46fa7f8557714250fb6f89c941ae","lessThan":"18ecd5b74682839e7cdafb7cd1ec106df7baa18c","status":"affected","versionType":"git"},{"version":"31d58c4e557d46fa7f8557714250fb6f89c941ae","lessThan":"bca2e29f7e26ce7c3522f8b324c0bd85612f68e3","status":"affected","versionType":"git"},{"version":"31d58c4e557d46fa7f8557714250fb6f89c941ae","lessThan":"d4fc4d01471528da8a9797a065982e05090e1d81","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/x86/coco/tdx/tdx.c"],"versions":[{"version":"5.19","status":"affected"},{"version":"0","lessThan":"5.19","status":"unaffected","versionType":"semver"},{"version":"6.1.113","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.54","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.10.13","lessThanOrEqual":"6.10.*","status":"unaffected","versionType":"semver"},{"version":"6.11.2","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.1.113"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.6.54"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.10.13"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.11.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/25703a3c980e21548774eea8c8a87a75c5c8f58c"},{"url":"https://git.kernel.org/stable/c/4c0c5dcb5471de5fc8f0a1c4980e5815339e1cee"},{"url":"https://git.kernel.org/stable/c/18ecd5b74682839e7cdafb7cd1ec106df7baa18c"},{"url":"https://git.kernel.org/stable/c/bca2e29f7e26ce7c3522f8b324c0bd85612f68e3"},{"url":"https://git.kernel.org/stable/c/d4fc4d01471528da8a9797a065982e05090e1d81"}],"title":"x86/tdx: Fix \"in-kernel MMIO\" check","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-47727","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-10-21T13:01:01.673306Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-10-21T13:04:16.452Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T22:21:23.601Z"}}]}}
