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-2023-52910 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-2023-52910/ (Markdown: https://insights.sbomify.com/CVE-2023-52910/index.md)","id":"CVE-2023-52910","markdown":"https://insights.sbomify.com/CVE-2023-52910/index.md","name":"CVE-2023-52910","record":{"aliases":["BELL-CVE-2023-52910","DEBIAN-CVE-2023-52910","GHSA-f5pw-c669-x4x7","UBUNTU-CVE-2023-52910"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An integer overflow in the Linux kernel IOMMU allocator can cause incorrect memory allocation, potentially leading to system instability or denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\niommu/iova: Fix alloc iova overflows issue\n\nIn __alloc_and_insert_iova_range, there is an issue that retry_pfn\noverflows. The value of iovad-\u003eanchor.pfn_hi is ~0UL, then when\niovad-\u003ecached_node is iovad-\u003eanchor, curr_iova-\u003epfn_hi + 1 will\noverflow. As a result, if the retry logic is executed, low_pfn is\nupdated to 0, and then new_pfn \u003c low_pfn returns false to make the\nallocation successful.\n\nThis issue occurs in the following two situations:\n1. The first iova size exceeds the domain size. When initializing\niova domain, iovad-\u003ecached_node is assigned as iovad-\u003eanchor. For\nexample, the iova domain size is 10M, start_pfn is 0x1_F000_0000,\nand the iova size allocated for the first time is 11M. The\nfollowing is the log information, new-\u003epfn_lo is smaller than\niovad-\u003ecached_node.\n\nExample log as follows:\n[  223.798112][T1705487] sh: [name:iova\u0026]__alloc_and_insert_iova_range\nstart_pfn:0x1f0000,retry_pfn:0x0,size:0xb00,limit_pfn:0x1f0a00\n[  223.799590][T1705487] sh: [name:iova\u0026]__alloc_and_insert_iova_range\nsuccess start_pfn:0x1f0000,new-\u003epfn_lo:0x1efe00,new-\u003epfn_hi:0x1f08ff\n\n2. The node with the largest iova-\u003epfn_lo value in the iova domain\nis deleted, iovad-\u003ecached_node will be updated to iovad-\u003eanchor,\nand then the alloc iova size exceeds the maximum iova size that can\nbe allocated in the domain.\n\nAfter judging that retry_pfn is less than limit_pfn, call retry_pfn+1\nto fix the overflow issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"iommu/iova: Fix alloc iova overflows issue","id":"CVE-2023-52910","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"integer_overflow","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"drm/msm: another fix for the headless Adreno GPU","id":"CVE-2023-52911"},"packages":[],"prev":{"headline":"nfsd: fix handling of cached open files in nfsd4_open codepath","id":"CVE-2023-52909"},"products":["Linux"],"published":"2024-08-21","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"An integer overflow in the Linux kernel IOMMU allocator can cause incorrect memory allocation, potentially leading to system instability or denial of service.","url":"https://insights.sbomify.com/CVE-2023-52910/"}
