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-2024-41085 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-2024-41085/ (Markdown: https://insights.sbomify.com/CVE-2024-41085/index.md)","id":"CVE-2024-41085","markdown":"https://insights.sbomify.com/CVE-2024-41085/index.md","name":"CVE-2024-41085","record":{"aliases":["AZL-48057","BELL-CVE-2024-41085","DEBIAN-CVE-2024-41085","GHSA-2qvq-p8h3-vf5j","UBUNTU-CVE-2024-41085"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel CXL driver","requires_auth":"low_privilege","summary":"A null pointer dereference in the Linux kernel CXL memory driver causes a system crash during PMEM region auto-assembly.","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\ncxl/mem: Fix no cxl_nvd during pmem region auto-assembling\n\nWhen CXL subsystem is auto-assembling a pmem region during cxl\nendpoint port probing, always hit below calltrace.\n\n BUG: kernel NULL pointer dereference, address: 0000000000000078\n #PF: supervisor read access in kernel mode\n #PF: error_code(0x0000) - not-present page\n RIP: 0010:cxl_pmem_region_probe+0x22e/0x360 [cxl_pmem]\n Call Trace:\n  \u003cTASK\u003e\n  ? __die+0x24/0x70\n  ? page_fault_oops+0x82/0x160\n  ? do_user_addr_fault+0x65/0x6b0\n  ? exc_page_fault+0x7d/0x170\n  ? asm_exc_page_fault+0x26/0x30\n  ? cxl_pmem_region_probe+0x22e/0x360 [cxl_pmem]\n  ? cxl_pmem_region_probe+0x1ac/0x360 [cxl_pmem]\n  cxl_bus_probe+0x1b/0x60 [cxl_core]\n  really_probe+0x173/0x410\n  ? __pfx___device_attach_driver+0x10/0x10\n  __driver_probe_device+0x80/0x170\n  driver_probe_device+0x1e/0x90\n  __device_attach_driver+0x90/0x120\n  bus_for_each_drv+0x84/0xe0\n  __device_attach+0xbc/0x1f0\n  bus_probe_device+0x90/0xa0\n  device_add+0x51c/0x710\n  devm_cxl_add_pmem_region+0x1b5/0x380 [cxl_core]\n  cxl_bus_probe+0x1b/0x60 [cxl_core]\n\nThe cxl_nvd of the memdev needs to be available during the pmem region\nprobe.
