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-2024-50227 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-2024-50227/ (Markdown: https://insights.sbomify.com/CVE-2024-50227/index.md)","id":"CVE-2024-50227","markdown":"https://insights.sbomify.com/CVE-2024-50227/index.md","name":"CVE-2024-50227","record":{"aliases":["BELL-CVE-2024-50227","DEBIAN-CVE-2024-50227","GHSA-qm24-fmqw-f5v5","UBUNTU-CVE-2024-50227"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel Thunderbolt","requires_auth":"low_privilege","summary":"A stack out-of-bounds read in the Linux kernel Thunderbolt driver allows attackers to cause a denial of service or leak sensitive kernel memory.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nthunderbolt: Fix KASAN reported stack out-of-bounds read in tb_retimer_scan()\n\nKASAN reported following issue:\n\n BUG: KASAN: stack-out-of-bounds in tb_retimer_scan+0xffe/0x1550 [thunderbolt]\n Read of size 4 at addr ffff88810111fc1c by task kworker/u56:0/11\n CPU: 0 UID: 0 PID: 11 Comm: kworker/u56:0 Tainted: G     U             6.11.0+ #1387\n Tainted: [U]=USER\n Workqueue: thunderbolt0 tb_handle_hotplug [thunderbolt]\n Call Trace:\n  \u003cTASK\u003e\n  dump_stack_lvl+0x6c/0x90\n  print_report+0xd1/0x630\n  kasan_report+0xdb/0x110\n  __asan_report_load4_noabort+0x14/0x20\n  tb_retimer_scan+0xffe/0x1550 [thunderbolt]\n  tb_scan_port+0xa6f/0x2060 [thunderbolt]\n  tb_handle_hotplug+0x17b1/0x3080 [thunderbolt]\n  process_one_work+0x626/0x1100\n  worker_thread+0x6c8/0xfa0\n  kthread+0x2c8/0x3a0\n  ret_from_fork+0x3a/0x80\n  ret_from_fork_asm+0x1a/0x30\n\nThis happens because the loop variable still gets incremented by one so\nmax becomes 3 instead of 2, and this makes the second loop read past the\nthe array declared on the stack.\n\nFix this by assigning to max directly in the loop body.","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":"thunderbolt: Fix KASAN reported stack out-of-bounds read in tb_retimer_scan()","id":"CVE-2024-50227","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"memory_corruption","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2024-50228"},"packages":[],"prev":{"headline":"cxl/port: Fix use-after-free, permit out-of-order decoder shutdown","id":"CVE-2024-50226"},"products":["Linux"],"published":"2024-11-09","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 stack out-of-bounds read in the Linux kernel Thunderbolt driver allows attackers to cause a denial of service or leak sensitive kernel memory.","url":"https://insights.sbomify.com/CVE-2024-50227/"}
