It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-38610 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-38610/ (Markdown: https://insights.sbomify.com/CVE-2024-38610/index.md)","id":"CVE-2024-38610","markdown":"https://insights.sbomify.com/CVE-2024-38610/index.md","name":"CVE-2024-38610","record":{"aliases":["BELL-CVE-2024-38610","DEBIAN-CVE-2024-38610","GHSA-h3h3-jq7c-xgpc","UBUNTU-CVE-2024-38610"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel ACRN driver","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel ACRN driver allows attackers to execute arbitrary code or escalate privileges via improper PTE checks.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrivers/virt/acrn: fix PFNMAP PTE checks in acrn_vm_ram_map()\n\nPatch series \"mm: follow_pte() improvements and acrn follow_pte() fixes\".\n\nPatch #1 fixes a bunch of issues I spotted in the acrn driver.  It\ncompiles, that's all I know.  I'll appreciate some review and testing from\nacrn folks.\n\nPatch #2+#3 improve follow_pte(), passing a VMA instead of the MM, adding\nmore sanity checks, and improving the documentation.  Gave it a quick test\non x86-64 using VM_PAT that ends up using follow_pte().\n\nThis patch (of 3):\n\nWe currently miss handling various cases, resulting in a dangerous\nfollow_pte() (previously follow_pfn()) usage.\n\n(1) We're not checking PTE write permissions.\n\nMaybe we should simply always require pte_write() like we do for\npin_user_pages_fast(FOLL_WRITE)?

Let's make sure to reject them.\n\n(3) We are only looking at the first PTE of a bigger range.\n\nWe only lookup a single PTE, but memmap-\u003elen may span a larger area.\nLet's loop over all involved PTEs and make sure the PFN range is\nactually contiguous.
