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-2024-46735 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-2024-46735/ (Markdown: https://insights.sbomify.com/CVE-2024-46735/index.md)","id":"CVE-2024-46735","markdown":"https://insights.sbomify.com/CVE-2024-46735/index.md","name":"CVE-2024-46735","record":{"aliases":["BELL-CVE-2024-46735","DEBIAN-CVE-2024-46735","GHSA-h642-rg9x-ww4c","UBUNTU-CVE-2024-46735"],"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 local attacker can trigger a kernel crash by submitting duplicate recovery commands to the ublk driver, causing a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nublk_drv: fix NULL pointer dereference in ublk_ctrl_start_recovery()\n\nWhen two UBLK_CMD_START_USER_RECOVERY commands are submitted, the\nfirst one sets 'ubq-\u003eubq_daemon' to NULL, and the second one triggers\nWARN in ublk_queue_reinit() and subsequently a NULL pointer dereference\nissue.\n\nFix it by adding the check in ublk_ctrl_start_recovery() and return\nimmediately in case of zero 'ub-\u003enr_queues_ready'.\n\n  BUG: kernel NULL pointer dereference, address: 0000000000000028\n  RIP: 0010:ublk_ctrl_start_recovery.constprop.0+0x82/0x180\n  Call Trace:\n   \u003cTASK\u003e\n   ? __die+0x20/0x70\n   ? page_fault_oops+0x75/0x170\n   ? exc_page_fault+0x64/0x140\n   ? asm_exc_page_fault+0x22/0x30\n   ? ublk_ctrl_start_recovery.constprop.0+0x82/0x180\n   ublk_ctrl_uring_cmd+0x4f7/0x6c0\n   ? pick_next_task_idle+0x26/0x40\n   io_uring_cmd+0x9a/0x1b0\n   io_issue_sqe+0x193/0x3f0\n   io_wq_submit_work+0x9b/0x390\n   io_worker_handle_work+0x165/0x360\n   io_wq_worker+0xcb/0x2f0\n   ? finish_task_switch.isra.0+0x203/0x290\n   ? finish_task_switch.isra.0+0x203/0x290\n   ? __pfx_io_wq_worker+0x10/0x10\n   ret_from_fork+0x2d/0x50\n   ? __pfx_io_wq_worker+0x10/0x10\n   ret_from_fork_asm+0x1a/0x30\n   \u003c/TASK\u003e","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":"ublk_drv: fix NULL pointer dereference in ublk_ctrl_start_recovery()","id":"CVE-2024-46735","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2024"},"n_packages":0,"n_references":4,"next":{"headline":"smb: client: fix double put of @cfile in smb2_rename_path()","id":"CVE-2024-46736"},"packages":[],"prev":{"headline":"btrfs: fix race between direct IO write and fsync when using same fd","id":"CVE-2024-46734"},"products":["Linux"],"published":"2024-09-18","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 local attacker can trigger a kernel crash by submitting duplicate recovery commands to the ublk driver, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2024-46735/"}
