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-2024-44947 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2024-44947/ (Markdown: https://insights.sbomify.com/CVE-2024-44947/index.md)","id":"CVE-2024-44947","markdown":"https://insights.sbomify.com/CVE-2024-44947/index.md","name":"CVE-2024-44947","record":{"aliases":["AZL-49296","AZL-49307","BELL-CVE-2024-44947","DEBIAN-CVE-2024-44947","GHSA-xjwh-3rm6-w25h","UBUNTU-CVE-2024-44947"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Local attackers can read uninitialized kernel memory via mmap on systems without init-on-alloc enabled, leaking sensitive data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-665","name":"Improper Initialization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfuse: Initialize beyond-EOF page contents before setting uptodate\n\nfuse_notify_store(), unlike fuse_do_readpage(), does not enable page\nzeroing (because it can be used to change partial page contents).\n\nSo fuse_notify_store() must be more careful to fully initialize page\ncontents (including parts of the page that are beyond end-of-file)\nbefore marking the page uptodate.\n\nThe current code can leave beyond-EOF page contents uninitialized, which\nmakes these uninitialized page contents visible to userspace via mmap().\n\nThis is an information leak, but only affects systems which do not\nenable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the\ncorresponding kernel command line parameter).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2024-09-03","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2024-09-03T18:37:40Z","kind":"github_poc","ref":"https://github.com/Abdurahmon3236/CVE-2024-44947","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"fuse: Initialize beyond-EOF page contents before setting uptodate","id":"CVE-2024-44947","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"information_disclosure","year":"2024"},"n_packages":0,"n_references":9,"next":{"headline":"x86/mtrr: Check if fixed MTRRs exist before saving them","id":"CVE-2024-44948"},"packages":[],"prev":{"headline":"kcm: Serialise kcm_sendmsg() for the same socket.","id":"CVE-2024-44946"},"products":["Linux"],"published":"2024-09-02","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"Local attackers can read uninitialized kernel memory via mmap on systems without init-on-alloc enabled, leaking sensitive data.","url":"https://insights.sbomify.com/CVE-2024-44947/"}
