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-2026-53061/ (Markdown: https://insights.sbomify.com/CVE-2026-53061/index.md)","id":"CVE-2026-53061","markdown":"https://insights.sbomify.com/CVE-2026-53061/index.md","name":"CVE-2026-53061","record":{"aliases":["BELL-CVE-2026-53061","DEBIAN-CVE-2026-53061","GHSA-h3w6-62jw-v8p3","ROOT-OS-DEBIAN-11-CVE-2026-53061","ROOT-OS-DEBIAN-12-CVE-2026-53061","ROOT-OS-UBUNTU-2204-CVE-2026-53061","ROOT-OS-UBUNTU-2404-CVE-2026-53061","UBUNTU-CVE-2026-53061"],"analysis":null,"analysis_generated_by":null,"assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndm cache: fix dirty mapping checking in passthrough mode switching\n\nAs mentioned in commit 9b1cc9f251af (\"dm cache: share cache-metadata\nobject across inactive and active DM tables\"), dm-cache assumed table\nreload occurs after suspension, while LVM's table preload breaks this\nassumption. The dirty mapping check for passthrough mode was designed\naround this assumption and is performed during table creation, causing\nthe check to fail with preload while metadata updates are ongoing. This\nrisks loading dirty mappings into passthrough mode, resulting in data\nloss.\n\nReproduce steps:\n\n1. Create a writeback cache with zero migration_threshold to produce\n   dirty mappings\n\ndmsetup create cmeta --table \"0 8192 linear /dev/sdc 0\"\ndmsetup create cdata --table \"0 131072 linear /dev/sdc 8192\"\ndmsetup create corig --table \"0 262144 linear /dev/sdc 262144\"\ndd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1 oflag=direct\ndmsetup create cache --table \"0 262144 cache /dev/mapper/cmeta \\\n/dev/mapper/cdata /dev/mapper/corig 128 2 metadata2 writeback smq \\\n2 migration_threshold 0\"\n\n2.

Write to the first cache block to make it dirty\n\nfio --filename=/dev/mapper/cache --name=populate --rw=write --bs=4k \\\n--direct=1 --size=64k\n\n4. Resume the inactive table. Now it's possible to load the dirty block\n   into passthrough mode.\n\ndmsetup resume cache\n\nFix by moving the checks to the preresume phase to support table\npreloading.
