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-2024-50222 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-2024-50222/ (Markdown: https://insights.sbomify.com/CVE-2024-50222/index.md)","id":"CVE-2024-50222","markdown":"https://insights.sbomify.com/CVE-2024-50222/index.md","name":"CVE-2024-50222","record":{"aliases":["AZL-53156","BELL-CVE-2024-50222","DEBIAN-CVE-2024-50222","GHSA-78hj-7cr6-hq8q","UBUNTU-CVE-2024-50222"],"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 local attacker can cause a system hang and warning in the Linux kernel when specific highmem debug configurations are enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\niov_iter: fix copy_page_from_iter_atomic() if KMAP_LOCAL_FORCE_MAP\n\ngeneric/077 on x86_32 CONFIG_DEBUG_KMAP_LOCAL_FORCE_MAP=y with highmem,\non huge=always tmpfs, issues a warning and then hangs (interruptibly):\n\nWARNING: CPU: 5 PID: 3517 at mm/highmem.c:622 kunmap_local_indexed+0x62/0xc9\nCPU: 5 UID: 0 PID: 3517 Comm: cp Not tainted 6.12.0-rc4 #2\n...\ncopy_page_from_iter_atomic+0xa6/0x5ec\ngeneric_perform_write+0xf6/0x1b4\nshmem_file_write_iter+0x54/0x67\n\nFix copy_page_from_iter_atomic() by limiting it in that case\n(include/linux/skbuff.h skb_frag_must_loop() does similar).\n\nBut going forward, perhaps CONFIG_DEBUG_KMAP_LOCAL_FORCE_MAP is too\nsurprising, has outlived its usefulness, and should just be removed?","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":"iov_iter: fix copy_page_from_iter_atomic() if KMAP_LOCAL_FORCE_MAP","id":"CVE-2024-50222","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":3,"next":{"headline":"sched/numa: Fix the potential null pointer dereference in task_numa_work()","id":"CVE-2024-50223"},"packages":[],"prev":{"headline":"drm/amd/pm: Vangogh: Fix kernel memory out of bounds write","id":"CVE-2024-50221"},"products":["Linux"],"published":"2024-11-09","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":"total"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A local attacker can cause a system hang and warning in the Linux kernel when specific highmem debug configurations are enabled.","url":"https://insights.sbomify.com/CVE-2024-50222/"}
