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-2022-50493 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-2022-50493/ (Markdown: https://insights.sbomify.com/CVE-2022-50493/index.md)","id":"CVE-2022-50493","markdown":"https://insights.sbomify.com/CVE-2022-50493/index.md","name":"CVE-2022-50493","record":{"aliases":["DEBIAN-CVE-2022-50493","GHSA-j4m7-gjwp-4ff2","ROOT-OS-DEBIAN-11-CVE-2022-50493","UBUNTU-CVE-2022-50493"],"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":"none","summary":"A null pointer dereference in the qla2xxx SCSI driver causes a kernel crash when an I/O abort times out during CPU hotplug operations.","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":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Fix crash when I/O abort times out\n\nWhile performing CPU hotplug, a crash with the following stack was seen:\n\nCall Trace:\n     qla24xx_process_response_queue+0x42a/0x970 [qla2xxx]\n     qla2x00_start_nvme_mq+0x3a2/0x4b0 [qla2xxx]\n     qla_nvme_post_cmd+0x166/0x240 [qla2xxx]\n     nvme_fc_start_fcp_op.part.0+0x119/0x2e0 [nvme_fc]\n     blk_mq_dispatch_rq_list+0x17b/0x610\n     __blk_mq_sched_dispatch_requests+0xb0/0x140\n     blk_mq_sched_dispatch_requests+0x30/0x60\n     __blk_mq_run_hw_queue+0x35/0x90\n     __blk_mq_delay_run_hw_queue+0x161/0x180\n     blk_execute_rq+0xbe/0x160\n     __nvme_submit_sync_cmd+0x16f/0x220 [nvme_core]\n     nvmf_connect_admin_queue+0x11a/0x170 [nvme_fabrics]\n     nvme_fc_create_association.cold+0x50/0x3dc [nvme_fc]\n     nvme_fc_connect_ctrl_work+0x19/0x30 [nvme_fc]\n     process_one_work+0x1e8/0x3c0\n\nOn abort timeout, completion was called without checking if the I/O was\nalready completed.\n\nVerify that I/O and abort request are indeed outstanding before attempting\ncompletion.","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: qla2xxx: Fix crash when I/O abort times out","id":"CVE-2022-50493","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":"thermal: intel_powerclamp: Use get_cpu() instead of smp_processor_id() to avoid crash","id":"CVE-2022-50494"},"packages":[],"prev":{"headline":"drm/msm: fix use-after-free on probe deferral","id":"CVE-2022-50492"},"products":["Linux"],"published":"2025-10-04","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Linux"]},"summary":"A null pointer dereference in the qla2xxx SCSI driver causes a kernel crash when an I/O abort times out during CPU hotplug operations.","url":"https://insights.sbomify.com/CVE-2022-50493/"}
