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-2022-50047 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-2022-50047/ (Markdown: https://insights.sbomify.com/CVE-2022-50047/index.md)","id":"CVE-2022-50047","markdown":"https://insights.sbomify.com/CVE-2022-50047/index.md","name":"CVE-2022-50047","record":{"aliases":["DEBIAN-CVE-2022-50047","GHSA-6259-v4q8-ghq3","UBUNTU-CVE-2022-50047"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A null pointer dereference in the Marvell DSA driver causes a kernel crash when configuring unused ports, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"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-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: mv88e6060: prevent crash on an unused port\n\nIf the port isn't a CPU port nor a user port, 'cpu_dp'\nis a null pointer and a crash happened on dereferencing\nit in mv88e6060_setup_port():\n\n[    9.575872] Unable to handle kernel NULL pointer dereference at virtual address 00000014\n...\n[    9.942216]  mv88e6060_setup from dsa_register_switch+0x814/0xe84\n[    9.948616]  dsa_register_switch from mdio_probe+0x2c/0x54\n[    9.954433]  mdio_probe from really_probe.part.0+0x98/0x2a0\n[    9.960375]  really_probe.part.0 from driver_probe_device+0x30/0x10c\n[    9.967029]  driver_probe_device from __device_attach_driver+0xb8/0x13c\n[    9.973946]  __device_attach_driver from bus_for_each_drv+0x90/0xe0\n[    9.980509]  bus_for_each_drv from __device_attach+0x110/0x184\n[    9.986632]  __device_attach from bus_probe_device+0x8c/0x94\n[    9.992577]  bus_probe_device from deferred_probe_work_func+0x78/0xa8\n[    9.999311]  deferred_probe_work_func from process_one_work+0x290/0x73c\n[   10.006292]  process_one_work from worker_thread+0x30/0x4b8\n[   10.012155]  worker_thread from kthread+0xd4/0x10c\n[   10.017238]  kthread from ret_from_fork+0x14/0x3c","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":"net: dsa: mv88e6060: prevent crash on an unused port","id":"CVE-2022-50047","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2022"},"n_packages":0,"n_references":5,"next":{"headline":"netfilter: nf_tables: possible module reference underflow in error path","id":"CVE-2022-50048"},"packages":[],"prev":{"headline":"net/sunrpc: fix potential memory leaks in rpc_sysfs_xprt_state_change()","id":"CVE-2022-50046"},"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":"2026-05-11","vendors":["Linux"]},"summary":"A null pointer dereference in the Marvell DSA driver causes a kernel crash when configuring unused ports, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2022-50047/"}
