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-2026-98937/ (Markdown: https://insights.sbomify.com/CVE-2026-98937/index.md)","id":"CVE-2026-98937","markdown":"https://insights.sbomify.com/CVE-2026-98937/index.md","name":"CVE-2026-98937","record":{"aliases":["AZL-110729","BELL-CVE-2026-98937","DEBIAN-CVE-2026-98937","GHSA-5cg4-h7ff-5xr5","UBUNTU-CVE-2026-98937"],"analysis":null,"analysis_generated_by":null,"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\nperf/core: Check kernel access when kernel callchains are requested\n\nperf_event_open() currently gates perf_allow_kernel() only on\n!attr.exclude_kernel.\n\nHowever, users can still request kernel callchain collection with\nattr.exclude_callchain_kernel == 0 even when attr.exclude_kernel == 1.\nThat still requires kernel profiling privilege, but the existing check\ndoes not enforce it.\n\nUpdate the permission check to call perf_allow_kernel() when either\nkernel sampling is requested or kernel callchains are requested.\n\nThis keeps permission checks aligned with requested data and prevents\nunprivileged use of kernel callchain capture.","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":"perf/core: Check kernel access when kernel callchains are requested","id":"CVE-2026-98937","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"rust: irq: pass RegistrationInner as cookie to request_irq","id":"CVE-2026-98938"},"packages":[],"prev":{"headline":"wifi: ath11k: reset ar-\u003enum_stations on hardware start","id":"CVE-2026-98936"},"products":["Linux"],"published":"2026-10-23","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":"2026-10-26","vendors":["Linux"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-98937/"}
