An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-53110 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-2023-53110/ (Markdown: https://insights.sbomify.com/CVE-2023-53110/index.md)","id":"CVE-2023-53110","markdown":"https://insights.sbomify.com/CVE-2023-53110/index.md","name":"CVE-2023-53110","record":{"aliases":["BELL-CVE-2023-53110","DEBIAN-CVE-2023-53110","GHSA-vm5r-r7q6-4cwx","UBUNTU-CVE-2023-53110"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A race condition in the Linux kernel SMC-R module can cause a NULL pointer dereference, leading to a system panic and 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":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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/smc: fix NULL sndbuf_desc in smc_cdc_tx_handler()\n\nWhen performing a stress test on SMC-R by rmmod mlx5_ib driver\nduring the wrk/nginx test, we found that there is a probability\nof triggering a panic while terminating all link groups.\n\nThis issue dues to the race between smc_smcr_terminate_all()\nand smc_buf_create().\n\n\t\t\tsmc_smcr_terminate_all\n\nsmc_buf_create\n/* init */\nconn-\u003esndbuf_desc = NULL;\n...\n\n\t\t\t__smc_lgr_terminate\n\t\t\t\tsmc_conn_kill\n\t\t\t\t\tsmc_close_abort\n\t\t\t\t\t\tsmc_cdc_get_slot_and_msg_send\n\n\t\t\t__softirqentry_text_start\n\t\t\t\tsmc_wr_tx_process_cqe\n\t\t\t\t\tsmc_cdc_tx_handler\n\t\t\t\t\t\tREAD(conn-\u003esndbuf_desc-\u003elen);\n\t\t\t\t\t\t/* panic dues to NULL sndbuf_desc */\n\nconn-\u003esndbuf_desc = xxx;\n\nThis patch tries to fix the issue by always to check the sndbuf_desc\nbefore send any cdc msg, to make sure that no null pointer is\nseen during cqe processing.","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/smc: fix NULL sndbuf_desc in smc_cdc_tx_handler()","id":"CVE-2023-53110","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2023"},"n_packages":0,"n_references":5,"next":{"headline":"loop: Fix use-after-free issues","id":"CVE-2023-53111"},"packages":[],"prev":{"headline":"net: tunnels: annotate lockless accesses to dev-\u003eneeded_headroom","id":"CVE-2023-53109"},"products":["Linux"],"published":"2025-05-02","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A race condition in the Linux kernel SMC-R module can cause a NULL pointer dereference, leading to a system panic and denial of service.","url":"https://insights.sbomify.com/CVE-2023-53110/"}
