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-2026-63967 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-2026-63967/ (Markdown: https://insights.sbomify.com/CVE-2026-63967/index.md)","id":"CVE-2026-63967","markdown":"https://insights.sbomify.com/CVE-2026-63967/index.md","name":"CVE-2026-63967","record":{"aliases":["BELL-CVE-2026-63967","DEBIAN-CVE-2026-63967","GHSA-vghm-prgp-x82v","ROOT-OS-UBUNTU-2204-CVE-2026-63967","UBUNTU-CVE-2026-63967"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A local attacker can read uninitialized kernel stack memory via the ST LSM6DSX IMU driver's tagged FIFO interface, potentially exposing sensitive data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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: imu: st_lsm6dsx: fix stack leak in tagged FIFO buffer\n\nThe tagged FIFO path declares iio_buff on the stack with __aligned(8)\nbut no initializer, but there is a hole in the structure, which will\nthen leak to userspace as ST_LSM6DSX_SAMPLE_SIZE bytes (6) will be\ncopied, but the space between that and the timestamp are not\ninitialized.\n\nCommit c14edb4d0bdc (\"iio:imu:st_lsm6dsx Fix alignment and data leak\nissues\") moved the untagged FIFO path to a kzalloc'd buffer in hw-\u003escan,\nbut for the tagged path it only added the alignment qualifier and not\nthe initializer :(\n\nFix this by just zero-initializing the structure on the stack.","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: imu: st_lsm6dsx: fix stack leak in tagged FIFO buffer","id":"CVE-2026-63967","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"ipv6: fix possible infinite loop in fib6_select_path()","id":"CVE-2026-63968"},"packages":[],"prev":{"headline":"iio: imu: adis16550: fix stack leak in trigger handler","id":"CVE-2026-63966"},"products":["Linux"],"published":"2026-07-19","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":"2026-07-19","vendors":["Linux"]},"summary":"A local attacker can read uninitialized kernel stack memory via the ST LSM6DSX IMU driver's tagged FIFO interface, potentially exposing sensitive data.","url":"https://insights.sbomify.com/CVE-2026-63967/"}
