It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-93053 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-2026-93053/ (Markdown: https://insights.sbomify.com/CVE-2026-93053/index.md)","id":"CVE-2026-93053","markdown":"https://insights.sbomify.com/CVE-2026-93053/index.md","name":"CVE-2026-93053","record":{"aliases":["AZL-103004","BELL-CVE-2026-93053","DEBIAN-CVE-2026-93053","GHSA-wqw9-pm7j-m5rf","UBUNTU-CVE-2026-93053"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel accessibility","requires_auth":"high_privilege","summary":"A local attacker with root privileges can trigger an out-of-bounds write in the Linux kernel speakup module by overriding function names via sysfs, potentially leading to code execution.","user_interaction":"required","vuln_class":"memory_corruption"},"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\nspeakup: keyhelp: guard letter_offsets possible out-of-range indexing\n\nhelp_init() builds letter_offsets[] by using the first byte of each\nfunction name as an index via `(start \u0026 31) - 1`.
