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-2024-36925 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-2024-36925/ (Markdown: https://insights.sbomify.com/CVE-2024-36925/index.md)","id":"CVE-2024-36925","markdown":"https://insights.sbomify.com/CVE-2024-36925/index.md","name":"CVE-2024-36925","record":{"aliases":["AZL-42462","BELL-CVE-2024-36925","DEBIAN-CVE-2024-36925","UBUNTU-CVE-2024-36925"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A null pointer dereference in the Linux kernel causes a crash when using restricted DMA pools with dynamic SWIOTLB enabled.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nswiotlb: initialise restricted pool list_head when SWIOTLB_DYNAMIC=y\n\nUsing restricted DMA pools (CONFIG_DMA_RESTRICTED_POOL=y) in conjunction\nwith dynamic SWIOTLB (CONFIG_SWIOTLB_DYNAMIC=y) leads to the following\ncrash when initialising the restricted pools at boot-time:\n\n  | Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008\n  | Internal error: Oops: 0000000096000005 [#1] PREEMPT SMP\n  | pc : rmem_swiotlb_device_init+0xfc/0x1ec\n  | lr : rmem_swiotlb_device_init+0xf0/0x1ec\n  | Call trace:\n  |  rmem_swiotlb_device_init+0xfc/0x1ec\n  |  of_reserved_mem_device_init_by_idx+0x18c/0x238\n  |  of_dma_configure_id+0x31c/0x33c\n  |  platform_dma_configure+0x34/0x80\n\nfaddr2line reveals that the crash is in the list validation code:\n\n  include/linux/list.h:83\n  include/linux/rculist.h:79\n  include/linux/rculist.h:106\n  kernel/dma/swiotlb.c:306\n  kernel/dma/swiotlb.c:1695\n\nbecause add_mem_pool() is trying to list_add_rcu() to a NULL\n'mem-\u003epools'.\n\nFix the crash by initialising the 'mem-\u003epools' list_head in\nrmem_swiotlb_device_init() before calling add_mem_pool().","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":"swiotlb: initialise restricted pool list_head when SWIOTLB_DYNAMIC=y","id":"CVE-2024-36925","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2024"},"n_packages":0,"n_references":3,"next":{"headline":"powerpc/pseries/iommu: LPAR panics during boot up with a frozen PE","id":"CVE-2024-36926"},"packages":[],"prev":{"headline":"scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up()","id":"CVE-2024-36924"},"products":["Linux"],"published":"2024-05-30","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A null pointer dereference in the Linux kernel causes a crash when using restricted DMA pools with dynamic SWIOTLB enabled.","url":"https://insights.sbomify.com/CVE-2024-36925/"}
