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-2022-50497 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-2022-50497/ (Markdown: https://insights.sbomify.com/CVE-2022-50497/index.md)","id":"CVE-2022-50497","markdown":"https://insights.sbomify.com/CVE-2022-50497/index.md","name":"CVE-2022-50497","record":{"aliases":["DEBIAN-CVE-2022-50497","GHSA-vwgj-v875-v924","UBUNTU-CVE-2022-50497"],"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 shift-out-of-bounds error in the Linux kernel's binfmt_misc module can cause a system crash or undefined behavior when processing special flags.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","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\nbinfmt_misc: fix shift-out-of-bounds in check_special_flags\n\nUBSAN reported a shift-out-of-bounds warning:\n\n left shift of 1 by 31 places cannot be represented in type 'int'\n Call Trace:\n  \u003cTASK\u003e\n  __dump_stack lib/dump_stack.c:88 [inline]\n  dump_stack_lvl+0x8d/0xcf lib/dump_stack.c:106\n  ubsan_epilogue+0xa/0x44 lib/ubsan.c:151\n  __ubsan_handle_shift_out_of_bounds+0x1e7/0x208 lib/ubsan.c:322\n  check_special_flags fs/binfmt_misc.c:241 [inline]\n  create_entry fs/binfmt_misc.c:456 [inline]\n  bm_register_write+0x9d3/0xa20 fs/binfmt_misc.c:654\n  vfs_write+0x11e/0x580 fs/read_write.c:582\n  ksys_write+0xcf/0x120 fs/read_write.c:637\n  do_syscall_x64 arch/x86/entry/common.c:50 [inline]\n  do_syscall_64+0x34/0x80 arch/x86/entry/common.c:80\n  entry_SYSCALL_64_after_hwframe+0x63/0xcd\n RIP: 0033:0x4194e1\n\nSince the type of Node's flags is unsigned long, we should define these\nmacros with same type too.","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":"binfmt_misc: fix shift-out-of-bounds in check_special_flags","id":"CVE-2022-50497","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"integer_overflow","year":"2022"},"n_packages":0,"n_references":9,"next":{"headline":"eth: alx: take rtnl_lock on resume","id":"CVE-2022-50498"},"packages":[],"prev":{"headline":"dm cache: Fix UAF in destroy()","id":"CVE-2022-50496"},"products":["Linux"],"published":"2025-10-04","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A shift-out-of-bounds error in the Linux kernel's binfmt_misc module can cause a system crash or undefined behavior when processing special flags.","url":"https://insights.sbomify.com/CVE-2022-50497/"}
