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-2026-89858 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-2026-89858/ (Markdown: https://insights.sbomify.com/CVE-2026-89858/index.md)","id":"CVE-2026-89858","markdown":"https://insights.sbomify.com/CVE-2026-89858/index.md","name":"CVE-2026-89858","record":{"aliases":["AZL-101634","BELL-CVE-2026-89858","DEBIAN-CVE-2026-89858","GHSA-m82c-43pj-6cj6","UBUNTU-CVE-2026-89858"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A local attacker can trigger an out-of-bounds read in the qla2xxx SCSI driver to leak kernel stack memory to the device.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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\nscsi: qla2xxx: Bound image count in qla2x00_update_fru_versions()\n\nqla2x00_update_fru_versions() copies the user-supplied BSG request into\na fixed 256-byte stack buffer (bsg[DMA_POOL_SIZE]) and then iterates\nlist-\u003ecount times over the qla_image_version array embedded in that\nbuffer, advancing the image pointer each iteration. count is taken\ndirectly from user input with no upper bound, while only (DMA_POOL_SIZE\n- sizeof(list-\u003ecount)) / sizeof(struct qla_image_version) = 6 entries\nactually fit.
