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-2024-27005 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-2024-27005/ (Markdown: https://insights.sbomify.com/CVE-2024-27005/index.md)","id":"CVE-2024-27005","markdown":"https://insights.sbomify.com/CVE-2024-27005/index.md","name":"CVE-2024-27005","record":{"aliases":["AZL-59644","BELL-CVE-2024-27005","DEBIAN-CVE-2024-27005","GHSA-p672-9qr7-4cmf","ROOT-OS-DEBIAN-12-CVE-2024-27005","ROOT-OS-UBUNTU-2204-CVE-2024-27005","UBUNTU-CVE-2024-27005"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel interconnect subsystem allows invalid pointer access, potentially causing system crashes or denial of service.","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":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-667","name":"Improper Locking"},{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ninterconnect: Don't access req_list while it's being manipulated\n\nThe icc_lock mutex was split into separate icc_lock and icc_bw_lock\nmutexes in [1] to avoid lockdep splats. However, this didn't adequately\nprotect access to icc_node::req_list.\n\nThe icc_set_bw() function will eventually iterate over req_list while\nonly holding icc_bw_lock, but req_list can be modified while only\nholding icc_lock. This causes races between icc_set_bw(), of_icc_get(),\nand icc_put().\n\nExample A:\n\n  CPU0                               CPU1\n  ----                               ----\n  icc_set_bw(path_a)\n    mutex_lock(\u0026icc_bw_lock);\n                                     icc_put(path_b)\n                                       mutex_lock(\u0026icc_lock);\n    aggregate_requests()\n      hlist_for_each_entry(r, ...\n                                       hlist_del(...\n        \u003cr = invalid pointer\u003e\n\nExample B:\n\n  CPU0                               CPU1\n  ----                               ----\n  icc_set_bw(path_a)\n    mutex_lock(\u0026icc_bw_lock);\n                                     path_b = of_icc_get()\n                                       of_icc_get_by_index()\n                                         mutex_lock(\u0026icc_lock);\n                                         path_find()\n                                           path_init()\n    aggregate_requests()\n      hlist_for_each_entry(r, ...\n                                             hlist_add_head(...\n        \u003cr = invalid pointer\u003e\n\nFix this by ensuring icc_bw_lock is always held before manipulating\nicc_node::req_list. The additional places icc_bw_lock is held don't\nperform any memory allocations, so we should still be safe from the\noriginal lockdep splats that motivated the separate locks.\n\n[1] commit af42269c3523 (\"interconnect: Fix locking for runpm vs reclaim\")","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":"interconnect: Don't access req_list while it's being manipulated","id":"CVE-2024-27005","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":5,"next":{"headline":"thermal/debugfs: Add missing count increment to thermal_debug_tz_trip_up()","id":"CVE-2024-27006"},"packages":[],"prev":{"headline":"clk: Get runtime PM before walking tree during disable_unused","id":"CVE-2024-27004"},"products":["Linux"],"published":"2024-05-01","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":"2026-08-05","vendors":["Linux"]},"summary":"A race condition in the Linux kernel interconnect subsystem allows invalid pointer access, potentially causing system crashes or denial of service.","url":"https://insights.sbomify.com/CVE-2024-27005/"}
