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-2026-90135 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-2026-90135/ (Markdown: https://insights.sbomify.com/CVE-2026-90135/index.md)","id":"CVE-2026-90135","markdown":"https://insights.sbomify.com/CVE-2026-90135/index.md","name":"CVE-2026-90135","record":{"aliases":["AZL-102833","BELL-CVE-2026-90135","DEBIAN-CVE-2026-90135","GHSA-j74m-jp6j-hqp6","UBUNTU-CVE-2026-90135"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"none","summary":"A use-after-free in the Linux kernel network subsystem can cause a crash when reading debug files if device allocation fails.","user_interaction":"not_required","vuln_class":"use_after_free"},"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: add missing ref_tracker_dir_exit() to alloc_netdev_mqs()\n\nsashiko is reporting that trying to read /sys/kernel/debug/ref_tracker/*\ncauses use-afer-free crash when either alloc_percpu() or dev_addr_init()\nin alloc_netdev_mqs() failed, for commit 4d92b95ff2f9 (\"net: add net device\nrefcount tracker infrastructure\") added ref_tracker_dir_exit() to only\nfree_netdev() path.","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: add missing ref_tracker_dir_exit() to alloc_netdev_mqs()","id":"CVE-2026-90135","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"platform/x86/amd/hsmp: Reject negative power cap writes in hwmon","id":"CVE-2026-90136"},"packages":[],"prev":{"headline":"ntfs: fix kmap_local_page() usage in compress","id":"CVE-2026-90134"},"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":"2026-10-21","vendors":["Linux"]},"summary":"A use-after-free in the Linux kernel network subsystem can cause a crash when reading debug files if device allocation fails.","url":"https://insights.sbomify.com/CVE-2026-90135/"}
