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-2022-50269 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-2022-50269/ (Markdown: https://insights.sbomify.com/CVE-2022-50269/index.md)","id":"CVE-2022-50269","markdown":"https://insights.sbomify.com/CVE-2022-50269/index.md","name":"CVE-2022-50269","record":{"aliases":["DEBIAN-CVE-2022-50269","GHSA-22jx-v9jm-qjqq","UBUNTU-CVE-2022-50269"],"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 VKMS driver during module initialization failure can lead to resource exhaustion and 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":"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\ndrm/vkms: Fix memory leak in vkms_init()\n\nA memory leak was reported after the vkms module install failed.\n\nunreferenced object 0xffff88810bc28520 (size 16):\n  comm \"modprobe\", pid 9662, jiffies 4298009455 (age 42.590s)\n  hex dump (first 16 bytes):\n    01 01 00 64 81 88 ff ff 00 00 dc 0a 81 88 ff ff  ...d............\n  backtrace:\n    [\u003c00000000e7561ff8\u003e] kmalloc_trace+0x27/0x60\n    [\u003c000000000b1954a0\u003e] 0xffffffffc45200a9\n    [\u003c00000000abbf1da0\u003e] do_one_initcall+0xd0/0x4f0\n    [\u003c000000001505ee87\u003e] do_init_module+0x1a4/0x680\n    [\u003c00000000958079ad\u003e] load_module+0x6249/0x7110\n    [\u003c00000000117e4696\u003e] __do_sys_finit_module+0x140/0x200\n    [\u003c00000000f74b12d2\u003e] do_syscall_64+0x35/0x80\n    [\u003c000000008fc6fcde\u003e] entry_SYSCALL_64_after_hwframe+0x46/0xb0\n\nThe reason is that the vkms_init() returns without checking the return\nvalue of vkms_create(), and if the vkms_create() failed, the config\nallocated at the beginning of vkms_init() is leaked.\n\n vkms_init()\n   config = kmalloc(...) # config allocated\n   ...\n   return vkms_create() # vkms_create failed and config is leaked\n\nFix this problem by checking return value of vkms_create() and free the\nconfig if error happened.","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":"drm/vkms: Fix memory leak in vkms_init()","id":"CVE-2022-50269","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":4,"next":{"headline":"f2fs: fix the assign logic of iocb","id":"CVE-2022-50270"},"packages":[],"prev":{"headline":"mmc: moxart: fix return value check of mmc_add_host()","id":"CVE-2022-50268"},"products":["Linux"],"published":"2025-09-15","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 VKMS driver during module initialization failure can lead to resource exhaustion and denial of service.","url":"https://insights.sbomify.com/CVE-2022-50269/"}
