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-2026-90056 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-2026-90056/ (Markdown: https://insights.sbomify.com/CVE-2026-90056/index.md)","id":"CVE-2026-90056","markdown":"https://insights.sbomify.com/CVE-2026-90056/index.md","name":"CVE-2026-90056","record":{"aliases":["AZL-102948","BELL-CVE-2026-90056","DEBIAN-CVE-2026-90056","GHSA-gqc9-g66v-x8p5","UBUNTU-CVE-2026-90056"],"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 null pointer dereference in the Linux kernel FEC driver can cause a system crash during device removal or initialization failure.","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\nnet: fec: only stop PTP if it was initialized\n\nfec_ptp_init() is only called when fep-\u003ebufdesc_ex is available.\nHowever, fec_probe() unconditionally calls fec_ptp_stop() on the\nfailed_init path, and fec_drv_remove() unconditionally calls\nfec_ptp_stop() during device removal.\n\nCheck fep-\u003ebufdesc_ex before calling fec_ptp_stop() in both paths\nto avoid stopping PTP when it was not initialized.","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":"net: fec: only stop PTP if it was initialized","id":"CVE-2026-90056","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"slip: remove slip_hangup() to fix use-after-free in slip_receive_buf()","id":"CVE-2026-90057"},"packages":[],"prev":{"headline":"usb: atm: usbatm: fix invalid ci_range initialization","id":"CVE-2026-90055"},"products":["Linux"],"published":"2026-09-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A null pointer dereference in the Linux kernel FEC driver can cause a system crash during device removal or initialization failure.","url":"https://insights.sbomify.com/CVE-2026-90056/"}
