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-2022-49312 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-2022-49312/ (Markdown: https://insights.sbomify.com/CVE-2022-49312/index.md)","id":"CVE-2022-49312","markdown":"https://insights.sbomify.com/CVE-2022-49312/index.md","name":"CVE-2022-49312","record":{"aliases":["DEBIAN-CVE-2022-49312","GHSA-6735-jgp5-qf5j","UBUNTU-CVE-2022-49312"],"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 memory leak in the rtl8712 staging driver can lead to resource exhaustion and denial of service if initialization fails.","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":"cisa-adp","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\nstaging: rtl8712: fix a potential memory leak in r871xu_drv_init()\n\nIn r871xu_drv_init(), if r8712_init_drv_sw() fails, then the memory\nallocated by r8712_alloc_io_queue() in r8712_usb_dvobj_init() is not\nproperly released as there is no action will be performed by\nr8712_usb_dvobj_deinit().\nTo properly release it, we should call r8712_free_io_queue() in\nr8712_usb_dvobj_deinit().\n\nBesides, in r871xu_dev_remove(), r8712_usb_dvobj_deinit() will be called\nby r871x_dev_unload() under condition `padapter-\u003ebup` and\nr8712_free_io_queue() is called by r8712_free_drv_sw().\nHowever, r8712_usb_dvobj_deinit() does not rely on `padapter-\u003ebup` and\ncalling r8712_free_io_queue() in r8712_free_drv_sw() is negative for\nbetter understading the code.\nSo I move r8712_usb_dvobj_deinit() into r871xu_dev_remove(), and remove\nr8712_free_io_queue() from r8712_free_drv_sw().","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":"staging: rtl8712: fix a potential memory leak in r871xu_drv_init()","id":"CVE-2022-49312","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":5,"next":{"headline":"drivers: usb: host: Fix deadlock in oxu_bus_suspend()","id":"CVE-2022-49313"},"packages":[],"prev":{"headline":"drivers: staging: rtl8192bs: Fix deadlock in rtw_joinbss_event_prehandle()","id":"CVE-2022-49311"},"products":["Linux"],"published":"2025-02-26","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A memory leak in the rtl8712 staging driver can lead to resource exhaustion and denial of service if initialization fails.","url":"https://insights.sbomify.com/CVE-2022-49312/"}
