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-2022-50876 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2022-50876/ (Markdown: https://insights.sbomify.com/CVE-2022-50876/index.md)","id":"CVE-2022-50876","markdown":"https://insights.sbomify.com/CVE-2022-50876/index.md","name":"CVE-2022-50876","record":{"aliases":["DEBIAN-CVE-2022-50876","GHSA-6h2f-jvv5-3x53","UBUNTU-CVE-2022-50876"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel USB driver","requires_auth":"none","summary":"A buffer overflow in the Linux kernel MUSB USB gadget driver allows attackers with physical access to cause memory corruption or system crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: musb: Fix musb_gadget.c rxstate overflow bug\n\nThe usb function device call musb_gadget_queue() adds the passed\nrequest to musb_ep::req_list,If the (request-\u003elength \u003e musb_ep-\u003epacket_sz)\nand (is_buffer_mapped(req) return false),the rxstate() will copy all data\nin fifo to request-\u003ebuf which may cause request-\u003ebuf out of bounds.\n\nFix it by add the length check :\nfifocnt = min_t(unsigned, request-\u003elength - request-\u003eactual, fifocnt);","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":"usb: musb: Fix musb_gadget.c rxstate overflow bug","id":"CVE-2022-50876","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":9,"next":{"headline":"net: broadcom: bcm4908_enet: update TX stats after actual transmission","id":"CVE-2022-50877"},"packages":[],"prev":{"headline":"of: overlay: fix null pointer dereferencing in find_dup_cset_node_entry() and find_dup_cset_prop()","id":"CVE-2022-50875"},"products":["Linux"],"published":"2025-12-30","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A buffer overflow in the Linux kernel MUSB USB gadget driver allows attackers with physical access to cause memory corruption or system crashes.","url":"https://insights.sbomify.com/CVE-2022-50876/"}
