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-2022-50581 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-2022-50581/ (Markdown: https://insights.sbomify.com/CVE-2022-50581/index.md)","id":"CVE-2022-50581","markdown":"https://insights.sbomify.com/CVE-2022-50581/index.md","name":"CVE-2022-50581","record":{"aliases":["DEBIAN-CVE-2022-50581","GHSA-w7j9-m3x4-j6vr","UBUNTU-CVE-2022-50581"],"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 HFS","requires_auth":"low_privilege","summary":"An out-of-bounds read in the Linux kernel HFS filesystem allows attackers to cause a denial of service or leak sensitive memory information.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nhfs: fix OOB Read in __hfs_brec_find\n\nSyzbot reported a OOB read bug:\n\n==================================================================\nBUG: KASAN: slab-out-of-bounds in hfs_strcmp+0x117/0x190\nfs/hfs/string.c:84\nRead of size 1 at addr ffff88807eb62c4e by task kworker/u4:1/11\nCPU: 1 PID: 11 Comm: kworker/u4:1 Not tainted\n6.1.0-rc6-syzkaller-00308-g644e9524388a #0\nWorkqueue: writeback wb_workfn (flush-7:0)\nCall Trace:\n \u003cTASK\u003e\n __dump_stack lib/dump_stack.c:88 [inline]\n dump_stack_lvl+0x1b1/0x28e lib/dump_stack.c:106\n print_address_description+0x74/0x340 mm/kasan/report.c:284\n print_report+0x107/0x1f0 mm/kasan/report.c:395\n kasan_report+0xcd/0x100 mm/kasan/report.c:495\n hfs_strcmp+0x117/0x190 fs/hfs/string.c:84\n __hfs_brec_find+0x213/0x5c0 fs/hfs/bfind.c:75\n hfs_brec_find+0x276/0x520 fs/hfs/bfind.c:138\n hfs_write_inode+0x34c/0xb40 fs/hfs/inode.c:462\n write_inode fs/fs-writeback.c:1440 [inline]\n\nIf the input inode of hfs_write_inode() is incorrect:\nstruct inode\n  struct hfs_inode_info\n    struct hfs_cat_key\n      struct hfs_name\n        u8 len # len is greater than HFS_NAMELEN(31) which is the\nmaximum length of an HFS filename\n\nOOB read occurred:\nhfs_write_inode()\n  hfs_brec_find()\n    __hfs_brec_find()\n      hfs_cat_keycmp()\n        hfs_strcmp() # OOB read occurred due to len is too large\n\nFix this by adding a Check on len in hfs_write_inode() before calling\nhfs_brec_find().","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":"hfs: fix OOB Read in __hfs_brec_find","id":"CVE-2022-50581","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":"regulator: core: Prevent integer underflow","id":"CVE-2022-50582"},"packages":[],"prev":{"headline":"blk-throttle: prevent overflow while calculating wait time","id":"CVE-2022-50580"},"products":["Linux"],"published":"2025-10-22","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"An out-of-bounds read in the Linux kernel HFS filesystem allows attackers to cause a denial of service or leak sensitive memory information.","url":"https://insights.sbomify.com/CVE-2022-50581/"}
