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-2024-38600 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-2024-38600/ (Markdown: https://insights.sbomify.com/CVE-2024-38600/index.md)","id":"CVE-2024-38600","markdown":"https://insights.sbomify.com/CVE-2024-38600/index.md","name":"CVE-2024-38600","record":{"aliases":["BELL-CVE-2024-38600","DEBIAN-CVE-2024-38600","GHSA-3h59-8483-h44f","UBUNTU-CVE-2024-38600"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel ALSA","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel ALSA subsystem can cause a deadlock during device disconnection, leading to a 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":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-667","name":"Improper Locking"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: Fix deadlocks with kctl removals at disconnection\n\nIn snd_card_disconnect(), we set card-\u003eshutdown flag at the beginning,\ncall callbacks and do sync for card-\u003epower_ref_sleep waiters at the\nend.  The callback may delete a kctl element, and this can lead to a\ndeadlock when the device was in the suspended state.  Namely:\n\n* A process waits for the power up at snd_power_ref_and_wait() in\n  snd_ctl_info() or read/write() inside card-\u003econtrols_rwsem.\n\n* The system gets disconnected meanwhile, and the driver tries to\n  delete a kctl via snd_ctl_remove*(); it tries to take\n  card-\u003econtrols_rwsem again, but this is already locked by the\n  above.  Since the sleeper isn't woken up, this deadlocks.\n\nAn easy fix is to wake up sleepers before processing the driver\ndisconnect callbacks but right after setting the card-\u003eshutdown flag.\nThen all sleepers will abort immediately, and the code flows again.\n\nSo, basically this patch moves the wait_event() call at the right\ntiming.  While we're at it, just to be sure, call wait_event_all()\ninstead of wait_event(), although we don't use exclusive events on\nthis queue for now.","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":"ALSA: Fix deadlocks with kctl removals at disconnection","id":"CVE-2024-38600","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":6,"next":{"headline":"ring-buffer: Fix a race between readers and resize checks","id":"CVE-2024-38601"},"packages":[],"prev":{"headline":"jffs2: prevent xattr node from overflowing the eraseblock","id":"CVE-2024-38599"},"products":["Linux"],"published":"2024-06-19","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":"2026-05-11","vendors":["Linux"]},"summary":"A race condition in the Linux kernel ALSA subsystem can cause a deadlock during device disconnection, leading to a denial of service.","url":"https://insights.sbomify.com/CVE-2024-38600/"}
