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-2024-56700 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-2024-56700/ (Markdown: https://insights.sbomify.com/CVE-2024-56700/index.md)","id":"CVE-2024-56700","markdown":"https://insights.sbomify.com/CVE-2024-56700/index.md","name":"CVE-2024-56700","record":{"aliases":["BELL-CVE-2024-56700","DEBIAN-CVE-2024-56700","GHSA-2hfg-4m2j-678g","UBUNTU-CVE-2024-56700"],"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 race condition in the wl128x media driver can cause a null pointer dereference, leading to a system crash.","user_interaction":"not_required","vuln_class":"race_condition"},"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\nmedia: wl128x: Fix atomicity violation in fmc_send_cmd()\n\nAtomicity violation occurs when the fmc_send_cmd() function is executed\nsimultaneously with the modification of the fmdev-\u003eresp_skb value.\nConsider a scenario where, after passing the validity check within the\nfunction, a non-null fmdev-\u003eresp_skb variable is assigned a null value.\nThis results in an invalid fmdev-\u003eresp_skb variable passing the validity\ncheck. As seen in the later part of the function, skb = fmdev-\u003eresp_skb;\nwhen the invalid fmdev-\u003eresp_skb passes the check, a null pointer\ndereference error may occur at line 478, evt_hdr = (void *)skb-\u003edata;\n\nTo address this issue, it is recommended to include the validity check of\nfmdev-\u003eresp_skb within the locked section of the function. This\nmodification ensures that the value of fmdev-\u003eresp_skb does not change\nduring the validation process, thereby maintaining its validity.\n\nThis possible bug is found by an experimental static analysis tool\ndeveloped by our team. This tool analyzes the locking APIs\nto extract function pairs that can be concurrently executed, and then\nanalyzes the instructions in the paired functions to identify possible\nconcurrency bugs including data races and atomicity violations.","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":"media: wl128x: Fix atomicity violation in fmc_send_cmd()","id":"CVE-2024-56700","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"race_condition","year":"2024"},"n_packages":0,"n_references":9,"next":{"headline":"powerpc/pseries: Fix dtl_access_lock to be a rw_semaphore","id":"CVE-2024-56701"},"packages":[],"prev":{"headline":"s390/pci: Fix potential double remove of hotplug slot","id":"CVE-2024-56699"},"products":["Linux"],"published":"2024-12-28","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A race condition in the wl128x media driver can cause a null pointer dereference, leading to a system crash.","url":"https://insights.sbomify.com/CVE-2024-56700/"}
