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-2024-26757 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-2024-26757/ (Markdown: https://insights.sbomify.com/CVE-2024-26757/index.md)","id":"CVE-2024-26757","markdown":"https://insights.sbomify.com/CVE-2024-26757/index.md","name":"CVE-2024-26757","record":{"aliases":["AZL-59480","AZL-59487","BELL-CVE-2024-26757","DEBIAN-CVE-2024-26757","GHSA-v63c-pgjm-vxv9","ROOT-OS-DEBIAN-11-CVE-2024-26757","ROOT-OS-DEBIAN-12-CVE-2024-26757","ROOT-OS-UBUNTU-2204-CVE-2024-26757","UBUNTU-CVE-2024-26757"],"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 flaw in the Linux kernel's md subsystem can cause a system hang when stopping a read-only array, leading to denial of service.","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":5.5,"severity":"medium","source":"cisa-adp","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-404","name":"Improper Resource Shutdown or Release"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd: Don't ignore read-only array in md_check_recovery()\n\nUsually if the array is not read-write, md_check_recovery() won't\nregister new sync_thread in the first place. And if the array is\nread-write and sync_thread is registered, md_set_readonly() will\nunregister sync_thread before setting the array read-only. md/raid\nfollow this behavior hence there is no problem.\n\nAfter commit f52f5c71f3d4 (\"md: fix stopping sync thread\"), following\nhang can be triggered by test shell/integrity-caching.sh:\n\n1) array is read-only. dm-raid update super block:\nrs_update_sbs\n ro = mddev-\u003ero\n mddev-\u003ero = 0\n  -\u003e set array read-write\n md_update_sb\n\n2) register new sync thread concurrently.\n\n3) dm-raid set array back to read-only:\nrs_update_sbs\n mddev-\u003ero = ro\n\n4) stop the array:\nraid_dtr\n md_stop\n  stop_sync_thread\n    set_bit(MD_RECOVERY_INTR, \u0026mddev-\u003erecovery);\n    md_wakeup_thread_directly(mddev-\u003esync_thread);\n    wait_event(..., !test_bit(MD_RECOVERY_RUNNING, \u0026mddev-\u003erecovery))\n\n5) sync thread done:\n md_do_sync\n set_bit(MD_RECOVERY_DONE, \u0026mddev-\u003erecovery);\n md_wakeup_thread(mddev-\u003ethread);\n\n6) daemon thread can't unregister sync thread:\n md_check_recovery\n  if (!md_is_rdwr(mddev) \u0026\u0026\n      !test_bit(MD_RECOVERY_NEEDED, \u0026mddev-\u003erecovery))\n   return;\n  -\u003e -\u003e MD_RECOVERY_RUNNING can't be cleared, hence step 4 hang;\n\nThe root cause is that dm-raid manipulate 'mddev-\u003ero' by itself,\nhowever, dm-raid really should stop sync thread before setting the\narray read-only.
