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-2022-49308 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-2022-49308/ (Markdown: https://insights.sbomify.com/CVE-2022-49308/index.md)","id":"CVE-2022-49308","markdown":"https://insights.sbomify.com/CVE-2022-49308/index.md","name":"CVE-2022-49308","record":{"aliases":["DEBIAN-CVE-2022-49308","GHSA-475c-87x7-jx25","UBUNTU-CVE-2022-49308"],"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 race condition in the Linux kernel extcon driver allows a local attacker to trigger a null pointer dereference and kernel Oops by reading sysfs attributes before driver data is initialized.","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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nextcon: Modify extcon device to be created after driver data is set\n\nCurrently, someone can invoke the sysfs such as state_show()\nintermittently before dev_set_drvdata() is done.\nAnd it can be a cause of kernel Oops because of edev is Null at that time.\nSo modified the driver registration to after setting drviver data.\n\n- Oops's backtrace.\n\nBacktrace:\n[\u003cc067865c\u003e] (state_show) from [\u003cc05222e8\u003e] (dev_attr_show)\n[\u003cc05222c0\u003e] (dev_attr_show) from [\u003cc02c66e0\u003e] (sysfs_kf_seq_show)\n[\u003cc02c6648\u003e] (sysfs_kf_seq_show) from [\u003cc02c496c\u003e] (kernfs_seq_show)\n[\u003cc02c4938\u003e] (kernfs_seq_show) from [\u003cc025e2a0\u003e] (seq_read)\n[\u003cc025e11c\u003e] (seq_read) from [\u003cc02c50a0\u003e] (kernfs_fop_read)\n[\u003cc02c5064\u003e] (kernfs_fop_read) from [\u003cc0231cac\u003e] (__vfs_read)\n[\u003cc0231c5c\u003e] (__vfs_read) from [\u003cc0231ee0\u003e] (vfs_read)\n[\u003cc0231e34\u003e] (vfs_read) from [\u003cc0232464\u003e] (ksys_read)\n[\u003cc02323f0\u003e] (ksys_read) from [\u003cc02324fc\u003e] (sys_read)\n[\u003cc02324e4\u003e] (sys_read) from [\u003cc00091d0\u003e] (__sys_trace_return)","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":"extcon: Modify extcon device to be created after driver data is set","id":"CVE-2022-49308","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":8,"next":{"headline":"drivers: staging: rtl8723bs: Fix deadlock in rtw_surveydone_event_callback()","id":"CVE-2022-49309"},"packages":[],"prev":{"headline":"tty: synclink_gt: Fix null-pointer-dereference in slgt_clean()","id":"CVE-2022-49307"},"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A race condition in the Linux kernel extcon driver allows a local attacker to trigger a null pointer dereference and kernel Oops by reading sysfs attributes before driver data is initialized.","url":"https://insights.sbomify.com/CVE-2022-49308/"}
