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-2026-90306 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-2026-90306/ (Markdown: https://insights.sbomify.com/CVE-2026-90306/index.md)","id":"CVE-2026-90306","markdown":"https://insights.sbomify.com/CVE-2026-90306/index.md","name":"CVE-2026-90306","record":{"aliases":["BELL-CVE-2026-90306","DEBIAN-CVE-2026-90306","GHSA-83wp-8ph8-8m42","UBUNTU-CVE-2026-90306"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"none","summary":"Fixes ARM kernel breakpoint handling to prevent interference with userspace breakpoints when CFI is disabled, ensuring correct fault reporting.","user_interaction":"not_required","vuln_class":"other"},"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\nARM: 9481/2: breakpoint: CFI breakpoints only on demand\n\nThis removes the stub hw_breakpoint_cfi_handler() from ARM, making\nit not steal breakpoint type 0x03 (ARM_ENTRY_CFI_BREAKPOINT) unless\nCFI is actively used in the kernel.\n\nWhen not instrumenting with CFI, or when a breakpoint is issued in\nuserspace, we fall through to return 1 from hw_breakpoint_pending()\n\"unhandled fault\" so userspace can make use of this breakpoint.\n\nTested with LKDTM and this command line:\necho CFI_FORWARD_PROTO \u003e /sys/kernel/debug/provoke-crash/DIRECT\nstill works as expected.","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":"ARM: 9481/2: breakpoint: CFI breakpoints only on demand","id":"CVE-2026-90306","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"RDMA/srp: fix heap information leak on a truncated SRP_CRED_REQ","id":"CVE-2026-90307"},"packages":[],"prev":{"headline":"ARM: 9483/1: select HAVE_POSIX_CPU_TIMERS_TASK_WORK","id":"CVE-2026-90305"},"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":"Fixes ARM kernel breakpoint handling to prevent interference with userspace breakpoints when CFI is disabled, ensuring correct fault reporting.","url":"https://insights.sbomify.com/CVE-2026-90306/"}
