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-2024-35917 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-2024-35917/ (Markdown: https://insights.sbomify.com/CVE-2024-35917/index.md)","id":"CVE-2024-35917","markdown":"https://insights.sbomify.com/CVE-2024-35917/index.md","name":"CVE-2024-35917","record":{"aliases":["BELL-CVE-2024-35917","DEBIAN-CVE-2024-35917","GHSA-6p8g-x822-g299","UBUNTU-CVE-2024-35917"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A pointer arithmetic error in the s390x BPF JIT compiler causes NULL pointer dereferences, leading to system crashes.","user_interaction":"not_required","vuln_class":"null_dereference"},"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:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ns390/bpf: Fix bpf_plt pointer arithmetic\n\nKui-Feng Lee reported a crash on s390x triggered by the\ndummy_st_ops/dummy_init_ptr_arg test [1]:\n\n  [\u003c0000000000000002\u003e] 0x2\n  [\u003c00000000009d5cde\u003e] bpf_struct_ops_test_run+0x156/0x250\n  [\u003c000000000033145a\u003e] __sys_bpf+0xa1a/0xd00\n  [\u003c00000000003319dc\u003e] __s390x_sys_bpf+0x44/0x50\n  [\u003c0000000000c4382c\u003e] __do_syscall+0x244/0x300\n  [\u003c0000000000c59a40\u003e] system_call+0x70/0x98\n\nThis is caused by GCC moving memcpy() after assignments in\nbpf_jit_plt(), resulting in NULL pointers being written instead of\nthe return and the target addresses.\n\nLooking at the GCC internals, the reordering is allowed because the\nalias analysis thinks that the memcpy() destination and the assignments'\nleft-hand-sides are based on different objects: new_plt and\nbpf_plt_ret/bpf_plt_target respectively, and therefore they cannot\nalias.\n\nThis is in turn due to a violation of the C standard:\n\n  When two pointers are subtracted, both shall point to elements of the\n  same array object, or one past the last element of the array object\n  ...\n\nFrom the C's perspective, bpf_plt_ret and bpf_plt are distinct objects\nand cannot be subtracted. In the practical terms, doing so confuses the\nGCC's alias analysis.\n\nThe code was written this way in order to let the C side know a few\noffsets defined in the assembly. While nice, this is by no means\nnecessary. Fix the noncompliance by hardcoding these offsets.\n\n[1] https://lore.kernel.org/bpf/c9923c1d-971d-4022-8dc8-1364e929d34c@gmail.com/","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":"s390/bpf: Fix bpf_plt pointer arithmetic","id":"CVE-2024-35917","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2024"},"n_packages":0,"n_references":3,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2024-35918"},"packages":[],"prev":{"headline":"dma-buf: Fix NULL pointer dereference in sanitycheck()","id":"CVE-2024-35916"},"products":["Linux"],"published":"2024-05-19","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":"2026-05-11","vendors":["Linux"]},"summary":"A pointer arithmetic error in the s390x BPF JIT compiler causes NULL pointer dereferences, leading to system crashes.","url":"https://insights.sbomify.com/CVE-2024-35917/"}
