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-2022-50076 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-2022-50076/ (Markdown: https://insights.sbomify.com/CVE-2022-50076/index.md)","id":"CVE-2022-50076","markdown":"https://insights.sbomify.com/CVE-2022-50076/index.md","name":"CVE-2022-50076","record":{"aliases":["DEBIAN-CVE-2022-50076","GHSA-hc4h-pg37-34f7","UBUNTU-CVE-2022-50076"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel CIFS","requires_auth":"low_privilege","summary":"A memory leak in the Linux kernel CIFS module allows attackers to cause denial of service by exhausting kernel memory through deferred close operations.","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\ncifs: Fix memory leak on the deferred close\n\nxfstests on smb21 report kmemleak as below:\n\n  unreferenced object 0xffff8881767d6200 (size 64):\n    comm \"xfs_io\", pid 1284, jiffies 4294777434 (age 20.789s)\n    hex dump (first 32 bytes):\n      80 5a d0 11 81 88 ff ff 78 8a aa 63 81 88 ff ff  .Z......x..c....\n      00 71 99 76 81 88 ff ff 00 00 00 00 00 00 00 00  .q.v............\n    backtrace:\n      [\u003c00000000ad04e6ea\u003e] cifs_close+0x92/0x2c0\n      [\u003c0000000028b93c82\u003e] __fput+0xff/0x3f0\n      [\u003c00000000d8116851\u003e] task_work_run+0x85/0xc0\n      [\u003c0000000027e14f9e\u003e] do_exit+0x5e5/0x1240\n      [\u003c00000000fb492b95\u003e] do_group_exit+0x58/0xe0\n      [\u003c00000000129a32d9\u003e] __x64_sys_exit_group+0x28/0x30\n      [\u003c00000000e3f7d8e9\u003e] do_syscall_64+0x35/0x80\n      [\u003c00000000102e8a0b\u003e] entry_SYSCALL_64_after_hwframe+0x46/0xb0\n\nWhen cancel the deferred close work, we should also cleanup the struct\ncifs_deferred_close.","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":"cifs: Fix memory leak on the deferred close","id":"CVE-2022-50076","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":3,"next":{"headline":"apparmor: fix reference count leak in aa_pivotroot()","id":"CVE-2022-50077"},"packages":[],"prev":{"headline":"tracing/eprobes: Have event probes be consistent with kprobes and uprobes","id":"CVE-2022-50075"},"products":["Linux"],"published":"2025-06-18","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-23","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel CIFS module allows attackers to cause denial of service by exhausting kernel memory through deferred close operations.","url":"https://insights.sbomify.com/CVE-2022-50076/"}
