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-2024-50021 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-2024-50021/ (Markdown: https://insights.sbomify.com/CVE-2024-50021/index.md)","id":"CVE-2024-50021","markdown":"https://insights.sbomify.com/CVE-2024-50021/index.md","name":"CVE-2024-50021","record":{"aliases":["BELL-CVE-2024-50021","DEBIAN-CVE-2024-50021","GHSA-r7rc-x5fw-x42q","UBUNTU-CVE-2024-50021"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A reference count leak in the Intel ice network driver can lead to resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"other"},"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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nice: Fix improper handling of refcount in ice_dpll_init_rclk_pins()\n\nThis patch addresses a reference count handling issue in the\nice_dpll_init_rclk_pins() function. The function calls ice_dpll_get_pins(),\nwhich increments the reference count of the relevant resources. However,\nif the condition WARN_ON((!vsi || !vsi-\u003enetdev)) is met, the function\ncurrently returns an error without properly releasing the resources\nacquired by ice_dpll_get_pins(), leading to a reference count leak.\n\nTo resolve this, the check has been moved to the top of the function. This\nensures that the function verifies the state before any resources are\nacquired, avoiding the need for additional resource management in the\nerror path.\n\nThis bug was identified by an experimental static analysis tool developed\nby our team. The tool specializes in analyzing reference count operations\nand detecting potential issues where resources are not properly managed.\nIn this case, the tool flagged the missing release operation as a\npotential problem, which led to the development of this patch.","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":"ice: Fix improper handling of refcount in ice_dpll_init_rclk_pins()","id":"CVE-2024-50021","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"other","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"device-dax: correct pgoff align in dax_set_mapping()","id":"CVE-2024-50022"},"packages":[],"prev":{"headline":"ice: Fix improper handling of refcount in ice_sriov_set_msix_vec_count()","id":"CVE-2024-50020"},"products":["Linux"],"published":"2024-10-21","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":"2026-05-11","vendors":["Linux"]},"summary":"A reference count leak in the Intel ice network driver can lead to resource exhaustion and denial of service.","url":"https://insights.sbomify.com/CVE-2024-50021/"}
