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-2026-99087/ (Markdown: https://insights.sbomify.com/CVE-2026-99087/index.md)","id":"CVE-2026-99087","markdown":"https://insights.sbomify.com/CVE-2026-99087/index.md","name":"CVE-2026-99087","record":{"aliases":["AZL-110993","BELL-CVE-2026-99087","DEBIAN-CVE-2026-99087","GHSA-458p-v4rq-r32g","UBUNTU-CVE-2026-99087"],"analysis":null,"analysis_generated_by":null,"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\ndm-integrity: fix NULL pointer dereference when the 'R' flag is used\n\nIf the dm-integrity device has the SB_FLAG_DIRTY_BITMAP flag set and the\nuser activates the device in the 'R' mode, a crash in dm_integrity_resume\nhappens because the function attempts to read the journal containing the\nbitmap.\n\nThis patch makes dm-integrity skip any writes to the device in\ndm_integrity_resume if the device is activated in the 'R' mode.","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":"dm-integrity: fix NULL pointer dereference when the 'R' flag is used","id":"CVE-2026-99087","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"net: openvswitch: validate transport header presence in set_ipv6_addr","id":"CVE-2026-99088"},"packages":[],"prev":{"headline":"dm-integrity: validate the superblock on resume","id":"CVE-2026-99086"},"products":["Linux"],"published":"2026-10-23","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":"2026-10-23","vendors":["Linux"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-99087/"}
