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-2024-26646 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-2024-26646/ (Markdown: https://insights.sbomify.com/CVE-2024-26646/index.md)","id":"CVE-2024-26646","markdown":"https://insights.sbomify.com/CVE-2024-26646/index.md","name":"CVE-2024-26646","record":{"aliases":["BELL-CVE-2024-26646","DEBIAN-CVE-2024-26646","GHSA-wrwp-f8pq-q3qj","UBUNTU-CVE-2024-26646"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A Linux kernel flaw allows memory corruption during hibernation or deep suspend resume, potentially enabling code execution or system crashes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nthermal: intel: hfi: Add syscore callbacks for system-wide PM\n\nThe kernel allocates a memory buffer and provides its location to the\nhardware, which uses it to update the HFI table. This allocation occurs\nduring boot and remains constant throughout runtime.\n\nWhen resuming from hibernation, the restore kernel allocates a second\nmemory buffer and reprograms the HFI hardware with the new location as\npart of a normal boot. The location of the second memory buffer may\ndiffer from the one allocated by the image kernel.\n\nWhen the restore kernel transfers control to the image kernel, its HFI\nbuffer becomes invalid, potentially leading to memory corruption if the\nhardware writes to it (the hardware continues to use the buffer from the\nrestore kernel).\n\nIt is also possible that the hardware \"forgets\" the address of the memory\nbuffer when resuming from \"deep\" suspend. Memory corruption may also occur\nin such a scenario.\n\nTo prevent the described memory corruption, disable HFI when preparing to\nsuspend or hibernate. Enable it when resuming.\n\nAdd syscore callbacks to handle the package of the boot CPU (packages of\nnon-boot CPUs are handled via CPU offline). Syscore ops always run on the\nboot CPU. Additionally, HFI only needs to be disabled during \"deep\" suspend\nand hibernation. Syscore ops only run in these cases.\n\n[ rjw: Comment adjustment, subject and changelog edits ]","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":"thermal: intel: hfi: Add syscore callbacks for system-wide PM","id":"CVE-2024-26646","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"memory_corruption","year":"2024"},"n_packages":0,"n_references":4,"next":{"headline":"drm/amd/display: Fix late derefrence 'dsc' check in 'link_set_dsc_pps_packet()'","id":"CVE-2024-26647"},"packages":[],"prev":{"headline":"tracing: Ensure visibility when inserting an element into tracing_map","id":"CVE-2024-26645"},"products":["Linux"],"published":"2024-03-26","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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-05","vendors":["Linux"]},"summary":"A Linux kernel flaw allows memory corruption during hibernation or deep suspend resume, potentially enabling code execution or system crashes.","url":"https://insights.sbomify.com/CVE-2024-26646/"}
