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-2026-93258 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-2026-93258/ (Markdown: https://insights.sbomify.com/CVE-2026-93258/index.md)","id":"CVE-2026-93258","markdown":"https://insights.sbomify.com/CVE-2026-93258/index.md","name":"CVE-2026-93258","record":{"aliases":["DEBIAN-CVE-2026-93258","GHSA-xg3j-cr9w-jr78","UBUNTU-CVE-2026-93258"],"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":"none","summary":"A flaw in the Linux kernel OCFS2 filesystem can cause a system crash during directory lookups due to incorrect inode handling.","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\nocfs2: do not use make_bad_inode() in ocfs2_read_inode_block_full()\n\nThis reverts commit 58b6fcd2ab34 (\"ocfs2: mark inode bad upon validation\nfailure during read\").\n\nSince 'make_bad_inode()' resets inode type to S_IFREG, doing this for\ndirectory inode during active VFS lookup is likely to confuse the latter,\nincluding VFS_BUG_ON_INODE() triggered in this case.","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":"ocfs2: do not use make_bad_inode() in ocfs2_read_inode_block_full()","id":"CVE-2026-93258","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"powerpc/irq: Fix missing r2 clobber in PCREL inline assembly","id":"CVE-2026-93259"},"packages":[],"prev":{"headline":"block: handle nogenerate/noverify properly in fs-integrity","id":"CVE-2026-93257"},"products":["Linux"],"published":"2026-09-24","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":"2026-10-19","vendors":["Linux"]},"summary":"A flaw in the Linux kernel OCFS2 filesystem can cause a system crash during directory lookups due to incorrect inode handling.","url":"https://insights.sbomify.com/CVE-2026-93258/"}
