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-2026-64498 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-2026-64498/ (Markdown: https://insights.sbomify.com/CVE-2026-64498/index.md)","id":"CVE-2026-64498","markdown":"https://insights.sbomify.com/CVE-2026-64498/index.md","name":"CVE-2026-64498","record":{"aliases":["DEBIAN-CVE-2026-64498","GHSA-vmjp-jvmv-9wwr","ROOT-OS-UBUNTU-2204-CVE-2026-64498","UBUNTU-CVE-2026-64498"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A missing memory free in the Linux kernel IIO subsystem can lead to memory corruption, potentially allowing local attackers to escalate privileges or cause a denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\niio: buffer: hw-consumer: free scan_mask on buffer release\n\nThe scan_mask lifetime changed in commit 9a2e1233d38c (\"iio: buffer:\nhw-consumer: remove redundant scan_mask flexible array\").\n\nBefore that change, the scan mask storage was embedded in struct\nhw_consumer_buffer, so iio_hw_buf_release() could free the whole\nallocation with a single kfree(hw_buf).\n\nThat commit moved the scan mask to a separate bitmap_zalloc() allocation\nstored in buffer.scan_mask, but left iio_hw_buf_release() unchanged.\n\nFree the scan mask in iio_hw_buf_release() before freeing the buffer\nwrapper.","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":"iio: buffer: hw-consumer: free scan_mask on buffer release","id":"CVE-2026-64498","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"iio: adc: ti-ads1119: fix PM reference leak in buffer preenable","id":"CVE-2026-64499"},"packages":[],"prev":{"headline":"iio: chemical: scd30: Cleanup initializations and fix sign-extension bug","id":"CVE-2026-64497"},"products":["Linux"],"published":"2026-07-25","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":"2026-08-17","vendors":["Linux"]},"summary":"A missing memory free in the Linux kernel IIO subsystem can lead to memory corruption, potentially allowing local attackers to escalate privileges or cause a denial of service.","url":"https://insights.sbomify.com/CVE-2026-64498/"}
