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-2022-49118 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-2022-49118/ (Markdown: https://insights.sbomify.com/CVE-2022-49118/index.md)","id":"CVE-2022-49118","markdown":"https://insights.sbomify.com/CVE-2022-49118/index.md","name":"CVE-2022-49118","record":{"aliases":["DEBIAN-CVE-2022-49118","GHSA-v6xc-xc9x-9pv7","UBUNTU-CVE-2022-49118"],"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 kernel bug in the hisi_sas driver causes a crash when probe fails, leading to denial of service.","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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: hisi_sas: Free irq vectors in order for v3 HW\n\nIf the driver probe fails to request the channel IRQ or fatal IRQ, the\ndriver will free the IRQ vectors before freeing the IRQs in free_irq(),\nand this will cause a kernel BUG like this:\n\n------------[ cut here ]------------\nkernel BUG at drivers/pci/msi.c:369!\nInternal error: Oops - BUG: 0 [#1] PREEMPT SMP\nCall trace:\n   free_msi_irqs+0x118/0x13c\n   pci_disable_msi+0xfc/0x120\n   pci_free_irq_vectors+0x24/0x3c\n   hisi_sas_v3_probe+0x360/0x9d0 [hisi_sas_v3_hw]\n   local_pci_probe+0x44/0xb0\n   work_for_cpu_fn+0x20/0x34\n   process_one_work+0x1d0/0x340\n   worker_thread+0x2e0/0x460\n   kthread+0x180/0x190\n   ret_from_fork+0x10/0x20\n---[ end trace b88990335b610c11 ]---\n\nSo we use devm_add_action() to control the order in which we free the\nvectors.","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":"scsi: hisi_sas: Free irq vectors in order for v3 HW","id":"CVE-2022-49118","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2022"},"n_packages":0,"n_references":5,"next":{"headline":"scsi: pm8001: Fix memory leak in pm8001_chip_fw_flash_update_req()","id":"CVE-2022-49119"},"packages":[],"prev":{"headline":"mips: ralink: fix a refcount leak in ill_acc_of_setup()","id":"CVE-2022-49117"},"products":["Linux"],"published":"2025-02-26","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-12","vendors":["Linux"]},"summary":"A kernel bug in the hisi_sas driver causes a crash when probe fails, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2022-49118/"}
