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-2024-35994 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-2024-35994/ (Markdown: https://insights.sbomify.com/CVE-2024-35994/index.md)","id":"CVE-2024-35994","markdown":"https://insights.sbomify.com/CVE-2024-35994/index.md","name":"CVE-2024-35994","record":{"aliases":["BELL-CVE-2024-35994","DEBIAN-CVE-2024-35994","GHSA-5jj7-rmfx-38vv","UBUNTU-CVE-2024-35994"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A memory allocation flaw in the Qualcomm UEFI Secure App driver can cause device hard-resets or IO errors, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: qcom: uefisecapp: Fix memory related IO errors and crashes\n\nIt turns out that while the QSEECOM APP_SEND command has specific fields\nfor request and response buffers, uefisecapp expects them both to be in\na single memory region. Failure to adhere to this has (so far) resulted\nin either no response being written to the response buffer (causing an\nEIO to be emitted down the line), the SCM call to fail with EINVAL\n(i.e., directly from TZ/firmware), or the device to be hard-reset.\n\nWhile this issue can be triggered deterministically, in the current form\nit seems to happen rather sporadically (which is why it has gone\nunnoticed during earlier testing). This is likely due to the two\nkzalloc() calls (for request and response) being directly after each\nother. Which means that those likely return consecutive regions most of\nthe time, especially when not much else is going on in the system.\n\nFix this by allocating a single memory region for both request and\nresponse buffers, properly aligning both structs inside it. This\nunfortunately also means that the qcom_scm_qseecom_app_send() interface\nneeds to be restructured, as it should no longer map the DMA regions\nseparately. Therefore, move the responsibility of DMA allocation (or\nmapping) to the caller.","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":"firmware: qcom: uefisecapp: Fix memory related IO errors and crashes","id":"CVE-2024-35994","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"ACPI: CPPC: Use access_width over bit_width for system memory accesses","id":"CVE-2024-35995"},"packages":[],"prev":{"headline":"mm: turn folio_test_hugetlb into a PageType","id":"CVE-2024-35993"},"products":["Linux"],"published":"2024-05-20","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 memory allocation flaw in the Qualcomm UEFI Secure App driver can cause device hard-resets or IO errors, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2024-35994/"}
