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-2026-43273/ (Markdown: https://insights.sbomify.com/CVE-2026-43273/index.md)","id":"CVE-2026-43273","markdown":"https://insights.sbomify.com/CVE-2026-43273/index.md","name":"CVE-2026-43273","record":{"aliases":["BELL-CVE-2026-43273","DEBIAN-CVE-2026-43273","GHSA-fcq7-vvcv-2qg9","ROOT-OS-DEBIAN-11-CVE-2026-43273","ROOT-OS-UBUNTU-2204-CVE-2026-43273","ROOT-OS-UBUNTU-2404-CVE-2026-43273","UBUNTU-CVE-2026-43273"],"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\nceph: supply snapshot context in ceph_zero_partial_object()\n\nThe ceph_zero_partial_object function was missing proper snapshot\ncontext for its OSD write operations, which could lead to data\ninconsistencies in snapshots.\n\nReproducer:\n../src/vstart.sh --new -x --localhost --bluestore\n./bin/ceph auth caps client.fs_a mds 'allow rwps fsname=a' mon 'allow r fsname=a' osd 'allow rw tag cephfs data=a'\nmount -t ceph fs_a@.a=/ /mnt/mycephfs/ -o conf=./ceph.conf\ndd if=/dev/urandom of=/mnt/mycephfs/foo bs=64K count=1\nmkdir /mnt/mycephfs/.snap/snap1\nmd5sum /mnt/mycephfs/.snap/snap1/foo\nfallocate -p -o 0 -l 4096 /mnt/mycephfs/foo\necho 3 \u003e /proc/sys/vm/drop/caches\nmd5sum /mnt/mycephfs/.snap/snap1/foo # get different md5sum!!","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":"ceph: supply snapshot context in ceph_zero_partial_object()","id":"CVE-2026-43273","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":null,"year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"mailbox: mchp-ipc-sbi: fix out-of-bounds access in mchp_ipc_get_cluster_aggr_irq()","id":"CVE-2026-43274"},"packages":[],"prev":{"headline":"ring-buffer: Fix possible dereference of uninitialized pointer","id":"CVE-2026-43272"},"products":["Linux"],"published":"2026-05-06","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-43273/"}
