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-2022-49925 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-2022-49925/ (Markdown: https://insights.sbomify.com/CVE-2022-49925/index.md)","id":"CVE-2022-49925","markdown":"https://insights.sbomify.com/CVE-2022-49925/index.md","name":"CVE-2022-49925","record":{"aliases":["DEBIAN-CVE-2022-49925","GHSA-mx7w-69f4-mg2q","UBUNTU-CVE-2022-49925"],"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 null pointer dereference in the Linux kernel RDMA core allows local attackers to cause a system crash by triggering a module cleanup failure.","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":"cisa-adp","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\nRDMA/core: Fix null-ptr-deref in ib_core_cleanup()\n\nKASAN reported a null-ptr-deref error:\n\n  KASAN: null-ptr-deref in range [0x0000000000000118-0x000000000000011f]\n  CPU: 1 PID: 379\n  Hardware name: QEMU Standard PC (i440FX + PIIX, 1996)\n  RIP: 0010:destroy_workqueue+0x2f/0x740\n  RSP: 0018:ffff888016137df8 EFLAGS: 00000202\n  ...\n  Call Trace:\n   ib_core_cleanup+0xa/0xa1 [ib_core]\n   __do_sys_delete_module.constprop.0+0x34f/0x5b0\n   do_syscall_64+0x3a/0x90\n   entry_SYSCALL_64_after_hwframe+0x63/0xcd\n  RIP: 0033:0x7fa1a0d221b7\n  ...\n\nIt is because the fail of roce_gid_mgmt_init() is ignored:\n\n ib_core_init()\n   roce_gid_mgmt_init()\n     gid_cache_wq = alloc_ordered_workqueue # fail\n ...\n ib_core_cleanup()\n   roce_gid_mgmt_cleanup()\n     destroy_workqueue(gid_cache_wq)\n     # destroy an unallocated wq\n\nFix this by catching the fail of roce_gid_mgmt_init() in ib_core_init().","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/core: Fix null-ptr-deref in ib_core_cleanup()","id":"CVE-2022-49925","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":"net: dsa: Fix possible memory leaks in dsa_loop_init()","id":"CVE-2022-49926"},"packages":[],"prev":{"headline":"nfc: fdp: Fix potential memory leak in fdp_nci_send()","id":"CVE-2022-49924"},"products":["Linux"],"published":"2025-05-01","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 null pointer dereference in the Linux kernel RDMA core allows local attackers to cause a system crash by triggering a module cleanup failure.","url":"https://insights.sbomify.com/CVE-2022-49925/"}
