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-2022-49807 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-2022-49807/ (Markdown: https://insights.sbomify.com/CVE-2022-49807/index.md)","id":"CVE-2022-49807","markdown":"https://insights.sbomify.com/CVE-2022-49807/index.md","name":"CVE-2022-49807","record":{"aliases":["DEBIAN-CVE-2022-49807","GHSA-wx6j-jwh7-wq64","UBUNTU-CVE-2022-49807"],"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 memory leak in the Linux kernel's nvmet authentication module allows attackers to exhaust system memory, potentially causing 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\nnvmet: fix a memory leak in nvmet_auth_set_key\n\nWhen changing dhchap secrets we need to release the old\nsecrets as well.\n\nkmemleak complaint:\n--\nunreferenced object 0xffff8c7f44ed8180 (size 64):\n  comm \"check\", pid 7304, jiffies 4295686133 (age 72034.246s)\n  hex dump (first 32 bytes):\n    44 48 48 43 2d 31 3a 30 30 3a 4c 64 4c 4f 64 71  DHHC-1:00:LdLOdq\n    79 56 69 67 77 48 55 32 6d 5a 59 4c 7a 35 59 38  yVigwHU2mZYLz5Y8\n  backtrace:\n    [\u003c00000000b6fc5071\u003e] kstrdup+0x2e/0x60\n    [\u003c00000000f0f4633f\u003e] 0xffffffffc0e07ee6\n    [\u003c0000000053006c05\u003e] 0xffffffffc0dff783\n    [\u003c00000000419ae922\u003e] configfs_write_iter+0xb1/0x120\n    [\u003c000000008183c424\u003e] vfs_write+0x2be/0x3c0\n    [\u003c000000009005a2a5\u003e] ksys_write+0x5f/0xe0\n    [\u003c00000000cd495c89\u003e] do_syscall_64+0x38/0x90\n    [\u003c00000000f2a84ac5\u003e] entry_SYSCALL_64_after_hwframe+0x63/0xcd","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":"nvmet: fix a memory leak in nvmet_auth_set_key","id":"CVE-2022-49807","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"net: dsa: don't leak tagger-owned storage on switch driver unbind","id":"CVE-2022-49808"},"packages":[],"prev":{"headline":"net: microchip: sparx5: Fix potential null-ptr-deref in sparx_stats_init() and sparx5_start()","id":"CVE-2022-49806"},"products":["Linux"],"published":"2025-05-01","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's nvmet authentication module allows attackers to exhaust system memory, potentially causing denial of service.","url":"https://insights.sbomify.com/CVE-2022-49807/"}
