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-2026-99154/ (Markdown: https://insights.sbomify.com/CVE-2026-99154/index.md)","id":"CVE-2026-99154","markdown":"https://insights.sbomify.com/CVE-2026-99154/index.md","name":"CVE-2026-99154","record":{"aliases":["AZL-111290","BELL-CVE-2026-99154","DEBIAN-CVE-2026-99154","GHSA-x6ph-vjqm-9q4f","UBUNTU-CVE-2026-99154"],"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\nscsi: libiscsi: Reject a negative task index from parse_pdu_itt\n\nA transport that implements parse_pdu_itt hands libiscsi an index taken\nfrom the PDU, and both lookups bound it from above only:\n\n      if (i \u003e= session-\u003ecmds_max)\n\ni and cmds_max are both int, so a negative index passes and\nsession-\u003ecmds[i] is read from before the array.\n\nbe2iscsi produces one. beiscsi_parse_pdu() assigns the raw tag,\n\n      *index = (int)itt;\n\nand beiscsi_complete_pdu() forwards an unsolicited NOP-In from the\nhardware async ring without replacing its ITT, so the value is the\ntarget's.
