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-2023-53670 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-2023-53670/ (Markdown: https://insights.sbomify.com/CVE-2023-53670/index.md)","id":"CVE-2023-53670","markdown":"https://insights.sbomify.com/CVE-2023-53670/index.md","name":"CVE-2023-53670","record":{"aliases":["BELL-CVE-2023-53670","DEBIAN-CVE-2023-53670","GHSA-hjjv-g993-99j8","UBUNTU-CVE-2023-53670"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel NVMe driver","requires_auth":"low_privilege","summary":"A memory leak in the Linux kernel NVMe driver during error handling can lead to resource exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnvme-core: fix dev_pm_qos memleak\n\nCall dev_pm_qos_hide_latency_tolerance() in the error unwind patch to\navoid following kmemleak:-\n\nblktests (master) # kmemleak-clear; ./check nvme/044;\nblktests (master) # kmemleak-scan ; kmemleak-show\nnvme/044 (Test bi-directional authentication)                [passed]\n    runtime  2.111s  ...  2.124s\nunreferenced object 0xffff888110c46240 (size 96):\n  comm \"nvme\", pid 33461, jiffies 4345365353 (age 75.586s)\n  hex dump (first 32 bytes):\n    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................\n    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................\n  backtrace:\n    [\u003c0000000069ac2cec\u003e] kmalloc_trace+0x25/0x90\n    [\u003c000000006acc66d5\u003e] dev_pm_qos_update_user_latency_tolerance+0x6f/0x100\n    [\u003c00000000cc376ea7\u003e] nvme_init_ctrl+0x38e/0x410 [nvme_core]\n    [\u003c000000007df61b4b\u003e] 0xffffffffc05e88b3\n    [\u003c00000000d152b985\u003e] 0xffffffffc05744cb\n    [\u003c00000000f04a4041\u003e] vfs_write+0xc5/0x3c0\n    [\u003c00000000f9491baf\u003e] ksys_write+0x5f/0xe0\n    [\u003c000000001c46513d\u003e] do_syscall_64+0x3b/0x90\n    [\u003c00000000ecf348fe\u003e] entry_SYSCALL_64_after_hwframe+0x72/0xdc","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":"nvme-core: fix dev_pm_qos memleak","id":"CVE-2023-53670","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"srcu: Delegate work to the boot cpu if using SRCU_SIZE_SMALL","id":"CVE-2023-53671"},"packages":[],"prev":{"headline":"tcp: fix skb_copy_ubufs() vs BIG TCP","id":"CVE-2023-53669"},"products":["Linux"],"published":"2025-10-07","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel NVMe driver during error handling can lead to resource exhaustion and denial of service.","url":"https://insights.sbomify.com/CVE-2023-53670/"}
