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-2026-98722 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-2026-98722/ (Markdown: https://insights.sbomify.com/CVE-2026-98722/index.md)","id":"CVE-2026-98722","markdown":"https://insights.sbomify.com/CVE-2026-98722/index.md","name":"CVE-2026-98722","record":{"aliases":["AZL-108917","BELL-CVE-2026-98722","DEBIAN-CVE-2026-98722","GHSA-9h6m-c947-v865","UBUNTU-CVE-2026-98722"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"high_privilege","summary":"A local attacker with high privileges can cause a kernel crash by setting a zero erase size in the block2mtd module parameter.","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\nmtd: block2mtd: Fix divide error when erase_size is zero\n\nThe erase size is parsed from the \"block2mtd\" module parameter and can\nbe set to zero. add_device() then evaluates\n\n        if (size % erase_size)\n\nwith a zero divisor, which triggers a divide error:\n\ndivide error: 0000 [#1] PREEMPT SMP PTI\nRIP: 0010:add_device drivers/mtd/devices/block2mtd.c:296 [inline]\nRIP: 0010:block2mtd_setup2+0x592/0xda0 drivers/mtd/devices/block2mtd.c:459\nCall Trace:\nblock2mtd_setup+0x27/0xe0 drivers/mtd/devices/block2mtd.c:476\nparam_attr_store+0x214/0x310 kernel/params.c:589\nmodule_attr_store+0x65/0x90 kernel/params.c:904\nkernfs_fop_write_iter+0x3a4/0x540 fs/kernfs/file.c:345\n...\n\nReject a zero erase size before performing the modulo operation so the\nexisting \"erasesize must be a divisor of device size\" error path\nreports the invalid argument and frees the device.","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":"mtd: block2mtd: Fix divide error when erase_size is zero","id":"CVE-2026-98722","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"nvmet: copy the hostid into the ctrl before creating PR pc_refs","id":"CVE-2026-98723"},"packages":[],"prev":{"headline":"mtd: rawnand: cadence: Initialize IRQ state before requesting IRQ","id":"CVE-2026-98721"},"products":["Linux"],"published":"2026-10-18","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":"2026-10-21","vendors":["Linux"]},"summary":"A local attacker with high privileges can cause a kernel crash by setting a zero erase size in the block2mtd module parameter.","url":"https://insights.sbomify.com/CVE-2026-98722/"}
