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-2022-49869 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-2022-49869/ (Markdown: https://insights.sbomify.com/CVE-2022-49869/index.md)","id":"CVE-2022-49869","markdown":"https://insights.sbomify.com/CVE-2022-49869/index.md","name":"CVE-2022-49869","record":{"aliases":["DEBIAN-CVE-2022-49869","GHSA-c7jg-hhpr-v5pq","UBUNTU-CVE-2022-49869"],"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":"low_privilege","summary":"A null pointer dereference in the bnxt_en network driver during error recovery can cause a kernel crash, leading to 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":5.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nbnxt_en: Fix possible crash in bnxt_hwrm_set_coal()\n\nDuring the error recovery sequence, the rtnl_lock is not held for the\nentire duration and some datastructures may be freed during the sequence.\nCheck for the BNXT_STATE_OPEN flag instead of netif_running() to ensure\nthat the device is fully operational before proceeding to reconfigure\nthe coalescing settings.\n\nThis will fix a possible crash like this:\n\nBUG: unable to handle kernel NULL pointer dereference at 0000000000000000\nPGD 0 P4D 0\nOops: 0000 [#1] SMP NOPTI\nCPU: 10 PID: 181276 Comm: ethtool Kdump: loaded Tainted: G          IOE    --------- -  - 4.18.0-348.el8.x86_64 #1\nHardware name: Dell Inc.
