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-2024-26838 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-2024-26838/ (Markdown: https://insights.sbomify.com/CVE-2024-26838/index.md)","id":"CVE-2024-26838","markdown":"https://insights.sbomify.com/CVE-2024-26838/index.md","name":"CVE-2024-26838","record":{"aliases":["BELL-CVE-2024-26838","DEBIAN-CVE-2024-26838","GHSA-4vhp-3pgf-3w85","UBUNTU-CVE-2024-26838"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel's irdma driver allows a use-after-free during IRQ deletion, potentially causing system crashes or code execution.","user_interaction":"not_required","vuln_class":"use_after_free"},"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-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nRDMA/irdma: Fix KASAN issue with tasklet\n\nKASAN testing revealed the following issue assocated with freeing an IRQ.\n\n[50006.466686] Call Trace:\n[50006.466691]  \u003cIRQ\u003e\n[50006.489538]  dump_stack+0x5c/0x80\n[50006.493475]  print_address_description.constprop.6+0x1a/0x150\n[50006.499872]  ? irdma_sc_process_ceq+0x483/0x790 [irdma]\n[50006.505742]  ? irdma_sc_process_ceq+0x483/0x790 [irdma]\n[50006.511644]  kasan_report.cold.11+0x7f/0x118\n[50006.516572]  ? irdma_sc_process_ceq+0x483/0x790 [irdma]\n[50006.522473]  irdma_sc_process_ceq+0x483/0x790 [irdma]\n[50006.528232]  irdma_process_ceq+0xb2/0x400 [irdma]\n[50006.533601]  ? irdma_hw_flush_wqes_callback+0x370/0x370 [irdma]\n[50006.540298]  irdma_ceq_dpc+0x44/0x100 [irdma]\n[50006.545306]  tasklet_action_common.isra.14+0x148/0x2c0\n[50006.551096]  __do_softirq+0x1d0/0xaf8\n[50006.555396]  irq_exit_rcu+0x219/0x260\n[50006.559670]  irq_exit+0xa/0x20\n[50006.563320]  smp_apic_timer_interrupt+0x1bf/0x690\n[50006.568645]  apic_timer_interrupt+0xf/0x20\n[50006.573341]  \u003c/IRQ\u003e\n\nThe issue is that a tasklet could be pending on another core racing\nthe delete of the irq.\n\nFix by insuring any scheduled tasklet is killed after deleting the\nirq.","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":"RDMA/irdma: Fix KASAN issue with tasklet","id":"CVE-2024-26838","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2024"},"n_packages":0,"n_references":5,"next":{"headline":"IB/hfi1: Fix a memleak in init_credit_return","id":"CVE-2024-26839"},"packages":[],"prev":{"headline":"net: bridge: switchdev: Skip MDB replays of deferred events on offload","id":"CVE-2024-26837"},"products":["Linux"],"published":"2024-04-17","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 race condition in the Linux kernel's irdma driver allows a use-after-free during IRQ deletion, potentially causing system crashes or code execution.","url":"https://insights.sbomify.com/CVE-2024-26838/"}
