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-2022-50706 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-2022-50706/ (Markdown: https://insights.sbomify.com/CVE-2022-50706/index.md)","id":"CVE-2022-50706","markdown":"https://insights.sbomify.com/CVE-2022-50706/index.md","name":"CVE-2022-50706","record":{"aliases":["DEBIAN-CVE-2022-50706","GHSA-xccr-4p75-vp7c","UBUNTU-CVE-2022-50706"],"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":"Local attackers can trigger a kernel warning and potential denial of service by sending zero-sized packets via IEEE802154 raw sockets.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nnet/ieee802154: don't warn zero-sized raw_sendmsg()\n\nsyzbot is hitting skb_assert_len() warning at __dev_queue_xmit() [1],\nfor PF_IEEE802154 socket's zero-sized raw_sendmsg() request is hitting\n__dev_queue_xmit() with skb-\u003elen == 0.\n\nSince PF_IEEE802154 socket's zero-sized raw_sendmsg() request was\nable to return 0, don't call __dev_queue_xmit() if packet length is 0.\n\n  ----------\n  #include \u003csys/socket.h\u003e\n  #include \u003cnetinet/in.h\u003e\n\n  int main(int argc, char *argv[])\n  {\n    struct sockaddr_in addr = { .sin_family = AF_INET, .sin_addr.s_addr = htonl(INADDR_LOOPBACK) };\n    struct iovec iov = { };\n    struct msghdr hdr = { .msg_name = \u0026addr, .msg_namelen = sizeof(addr), .msg_iov = \u0026iov, .msg_iovlen = 1 };\n    sendmsg(socket(PF_IEEE802154, SOCK_RAW, 0), \u0026hdr, 0);\n    return 0;\n  }\n  ----------\n\nNote that this might be a sign that commit fd1894224407c484 (\"bpf: Don't\nredirect packets with invalid pkt_len\") should be reverted, for\nskb-\u003elen == 0 was acceptable for at least PF_IEEE802154 socket.","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/ieee802154: don't warn zero-sized raw_sendmsg()","id":"CVE-2022-50706","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":6,"next":{"headline":"virtio-crypto: fix memory leak in virtio_crypto_alg_skcipher_close_session()","id":"CVE-2022-50707"},"packages":[],"prev":{"headline":"io_uring/rw: defer fsnotify calls to task context","id":"CVE-2022-50705"},"products":["Linux"],"published":"2025-12-24","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":"2026-05-23","vendors":["Linux"]},"summary":"Local attackers can trigger a kernel warning and potential denial of service by sending zero-sized packets via IEEE802154 raw sockets.","url":"https://insights.sbomify.com/CVE-2022-50706/"}
