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-2026-74683 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-2026-74683/ (Markdown: https://insights.sbomify.com/CVE-2026-74683/index.md)","id":"CVE-2026-74683","markdown":"https://insights.sbomify.com/CVE-2026-74683/index.md","name":"CVE-2026-74683","record":{"aliases":["AZL-97269","BELL-CVE-2026-74683","DEBIAN-CVE-2026-74683","GHSA-76mx-gxxj-5f36","UBUNTU-CVE-2026-74683"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can exploit speculative execution flaws in the Linux kernel evdev driver to read sensitive memory contents via out-of-bounds loads.","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\nInput: evdev - sanitize event type index when fetching event masks\n\nThe user-supplied event type index passed to EVIOCGMASK / EVIOCSMASK\nioctls is used to index the static counts array in evdev_get_mask_cnt()\nand client evmasks array in evdev_get_mask().\n\nWhile the event type is architecturally bounded by EV_CNT, speculative\nexecution may mispredict bounds checks and perform out-of-bounds loads.\n\nSanitize the event type index in evdev_get_mask_cnt() branchlessly using\narray_index_mask_nospec().
