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-2026-68195 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-2026-68195/ (Markdown: https://insights.sbomify.com/CVE-2026-68195/index.md)","id":"CVE-2026-68195","markdown":"https://insights.sbomify.com/CVE-2026-68195/index.md","name":"CVE-2026-68195","record":{"aliases":["BELL-CVE-2026-68195","DEBIAN-CVE-2026-68195","GHSA-p547-p22q-3vh3","UBUNTU-CVE-2026-68195"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel WiFi driver","requires_auth":"none","summary":"A null pointer dereference in the mt7615 WiFi driver causes a kernel crash when processing specific packets on USB or SDIO buses.","user_interaction":"not_required","vuln_class":"null_dereference"},"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: mt76: mt7615: drop TXRX_NOTIFY on non-mmio buses\n\nPKT_TYPE_TXRX_NOTIFY is an mmio-only event, but mt7615_rx_check() and\nmt7615_queue_rx_skb() dispatch it to mt7615_mac_tx_free() on every bus.\nmt7615_mac_tx_free() cleans the DMA tx queues with\nmt76_queue_tx_cleanup(), which calls queue_ops-\u003etx_cleanup().
