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-2026-74368 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-2026-74368/ (Markdown: https://insights.sbomify.com/CVE-2026-74368/index.md)","id":"CVE-2026-74368","markdown":"https://insights.sbomify.com/CVE-2026-74368/index.md","name":"CVE-2026-74368","record":{"aliases":["BELL-CVE-2026-74368","DEBIAN-CVE-2026-74368","GHSA-jx2p-wmx4-9hvq","UBUNTU-CVE-2026-74368"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A memory leak in the ath12k Wi-Fi driver allows attackers to cause denial of service by triggering invalid header validation during TKIP MIC verification.","user_interaction":"not_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\nwifi: ath12k: fix memory leak in ath12k_wifi7_dp_rx_h_verify_tkip_mic()\n\nIn ath12k_wifi7_dp_rx_h_verify_tkip_mic(), the call to\nath12k_dp_rx_check_nwifi_hdr_len_valid() may return false when the\nNWIFI header length is invalid, causing the function to abort early with\n-EINVAL.\n\nWhen this happens, the error propagates to\nath12k_wifi7_dp_rx_h_defrag(), which clears first_frag by setting it\nto NULL.
