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-2026-53177 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-2026-53177/ (Markdown: https://insights.sbomify.com/CVE-2026-53177/index.md)","id":"CVE-2026-53177","markdown":"https://insights.sbomify.com/CVE-2026-53177/index.md","name":"CVE-2026-53177","record":{"aliases":["AZL-90312","BELL-CVE-2026-53177","DEBIAN-CVE-2026-53177","GHSA-fgqh-527q-6hx4","ROOT-OS-DEBIAN-11-CVE-2026-53177","ROOT-OS-DEBIAN-12-CVE-2026-53177","ROOT-OS-UBUNTU-2204-CVE-2026-53177","ROOT-OS-UBUNTU-2404-CVE-2026-53177","UBUNTU-CVE-2026-53177"],"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 driver during PCIe error recovery on a closed NIC 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":"nvd","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 NULL pointer dereference\n\nPCIe errors detected by a Root Port or Downstream Port cause error\nrecovery services to run on all subordinate devices regardless of\nadministrative state.\n\nThe .error_detected() callback, bnxt_io_error_detected(), disables\nand synchronizes IRQs via bnxt_disable_int_sync(), which calls\nbnxt_cp_num_to_irq_num() to map completion rings to IRQs using\nbp-\u003ebnapi.\n\nSince bp-\u003ebnapi is allocated on NIC open and freed on NIC close, PCIe\nerror recovery on a closed NIC can dereference a NULL pointer.\n\nCheck if bp-\u003ebnapi is NULL before disabling and synchronizing IRQs.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"bnxt_en: Fix NULL pointer dereference","id":"CVE-2026-53177","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"staging: rtl8723bs: rtw_mlme: add bounds checks before ie_length subtraction","id":"CVE-2026-53178"},"packages":[],"prev":{"headline":"IB/isert: Reject login PDUs shorter than ISER_HEADERS_LEN","id":"CVE-2026-53176"},"products":["Linux"],"published":"2026-06-25","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A NULL pointer dereference in the bnxt_en driver during PCIe error recovery on a closed NIC can cause a kernel crash, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2026-53177/"}
