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-2023-53852 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2023-53852/ (Markdown: https://insights.sbomify.com/CVE-2023-53852/index.md)","id":"CVE-2023-53852","markdown":"https://insights.sbomify.com/CVE-2023-53852/index.md","name":"CVE-2023-53852","record":{"aliases":["BELL-CVE-2023-53852","DEBIAN-CVE-2023-53852","GHSA-6p7c-22m4-r5fq","UBUNTU-CVE-2023-53852"],"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":"high_privilege","summary":"A memory leak in the Linux kernel NVMe driver allows local attackers to exhaust system memory, causing denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnvme-core: fix memory leak in dhchap_secret_store\n\nFree dhchap_secret in nvme_ctrl_dhchap_secret_store() before we return\nfix following kmemleack:-\n\nunreferenced object 0xffff8886376ea800 (size 64):\n  comm \"check\", pid 22048, jiffies 4344316705 (age 92.199s)\n  hex dump (first 32 bytes):\n    44 48 48 43 2d 31 3a 30 30 3a 6e 78 72 35 4b 67  DHHC-1:00:nxr5Kg\n    75 58 34 75 6f 41 78 73 4a 61 34 63 2f 68 75 4c  uX4uoAxsJa4c/huL\n  backtrace:\n    [\u003c0000000030ce5d4b\u003e] __kmalloc+0x4b/0x130\n    [\u003c000000009be1cdc1\u003e] nvme_ctrl_dhchap_secret_store+0x8f/0x160 [nvme_core]\n    [\u003c00000000ac06c96a\u003e] kernfs_fop_write_iter+0x12b/0x1c0\n    [\u003c00000000437e7ced\u003e] vfs_write+0x2ba/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\nunreferenced object 0xffff8886376eaf00 (size 64):\n  comm \"check\", pid 22048, jiffies 4344316736 (age 92.168s)\n  hex dump (first 32 bytes):\n    44 48 48 43 2d 31 3a 30 30 3a 6e 78 72 35 4b 67  DHHC-1:00:nxr5Kg\n    75 58 34 75 6f 41 78 73 4a 61 34 63 2f 68 75 4c  uX4uoAxsJa4c/huL\n  backtrace:\n    [\u003c0000000030ce5d4b\u003e] __kmalloc+0x4b/0x130\n    [\u003c000000009be1cdc1\u003e] nvme_ctrl_dhchap_secret_store+0x8f/0x160 [nvme_core]\n    [\u003c00000000ac06c96a\u003e] kernfs_fop_write_iter+0x12b/0x1c0\n    [\u003c00000000437e7ced\u003e] vfs_write+0x2ba/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 memory leak in dhchap_secret_store","id":"CVE-2023-53852","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"netlink: annotate accesses to nlk-\u003ecb_running","id":"CVE-2023-53853"},"packages":[],"prev":{"headline":"drm/msm/dp: Drop aux devices together with DP controller","id":"CVE-2023-53851"},"products":["Linux"],"published":"2025-12-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"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 allows local attackers to exhaust system memory, causing denial of service.","url":"https://insights.sbomify.com/CVE-2023-53852/"}
