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-2026-43213 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2026-43213/ (Markdown: https://insights.sbomify.com/CVE-2026-43213/index.md)","id":"CVE-2026-43213","markdown":"https://insights.sbomify.com/CVE-2026-43213/index.md","name":"CVE-2026-43213","record":{"aliases":["BELL-CVE-2026-43213","DEBIAN-CVE-2026-43213","GHSA-g35v-pp28-72vc","ROOT-OS-DEBIAN-11-CVE-2026-43213","ROOT-OS-DEBIAN-12-CVE-2026-43213","ROOT-OS-DEBIAN-13-CVE-2026-43213","ROOT-OS-UBUNTU-2204-CVE-2026-43213","ROOT-OS-UBUNTU-2404-CVE-2026-43213","UBUNTU-CVE-2026-43213"],"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 missing validation in the rtw89 WiFi driver allows a NULL pointer dereference, causing a kernel crash and denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw89: pci: validate sequence number of TX release report\n\nHardware rarely reports abnormal sequence number in TX release report,\nwhich will access out-of-bounds of wd_ring-\u003epages array, causing NULL\npointer dereference.\n\n  BUG: kernel NULL pointer dereference, address: 0000000000000000\n  #PF: supervisor read access in kernel mode\n  #PF: error_code(0x0000) - not-present page\n  PGD 0 P4D 0\n  Oops: 0000 [#1] PREEMPT SMP NOPTI\n  CPU: 1 PID: 1085 Comm: irq/129-rtw89_p Tainted: G S   U\n             6.1.145-17510-g2f3369c91536 #1 (HASH:69e8 1)\n  Call Trace:\n   \u003cIRQ\u003e\n   rtw89_pci_release_tx+0x18f/0x300 [rtw89_pci (HASH:4c83 2)]\n   rtw89_pci_napi_poll+0xc2/0x190 [rtw89_pci (HASH:4c83 2)]\n   net_rx_action+0xfc/0x460 net/core/dev.c:6578 net/core/dev.c:6645 net/core/dev.c:6759\n   handle_softirqs+0xbe/0x290 kernel/softirq.c:601\n   ?
