An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-49321 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-2022-49321/ (Markdown: https://insights.sbomify.com/CVE-2022-49321/index.md)","id":"CVE-2022-49321","markdown":"https://insights.sbomify.com/CVE-2022-49321/index.md","name":"CVE-2022-49321","record":{"aliases":["DEBIAN-CVE-2022-49321","GHSA-vch8-w6r9-fgp2","UBUNTU-CVE-2022-49321"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"A null pointer dereference in the Linux kernel's xprtrdma module allows a remote attacker to cause a system crash via a malformed RPC reply.","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":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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\nxprtrdma: treat all calls not a bcall when bc_serv is NULL\n\nWhen a rdma server returns a fault format reply, nfs v3 client may\ntreats it as a bcall when bc service is not exist.\n\nThe debug message at rpcrdma_bc_receive_call are,\n\n[56579.837169] RPC:       rpcrdma_bc_receive_call: callback XID\n00000001, length=20\n[56579.837174] RPC:       rpcrdma_bc_receive_call: 00 00 00 01 00 00 00\n00 00 00 00 00 00 00 00 00 00 00 00 04\n\nAfter that, rpcrdma_bc_receive_call will meets NULL pointer as,\n\n[  226.057890] BUG: unable to handle kernel NULL pointer dereference at\n00000000000000c8\n...\n[  226.058704] RIP: 0010:_raw_spin_lock+0xc/0x20\n...\n[  226.059732] Call Trace:\n[  226.059878]  rpcrdma_bc_receive_call+0x138/0x327 [rpcrdma]\n[  226.060011]  __ib_process_cq+0x89/0x170 [ib_core]\n[  226.060092]  ib_cq_poll_work+0x26/0x80 [ib_core]\n[  226.060257]  process_one_work+0x1a7/0x360\n[  226.060367]  ? create_worker+0x1a0/0x1a0\n[  226.060440]  worker_thread+0x30/0x390\n[  226.060500]  ? create_worker+0x1a0/0x1a0\n[  226.060574]  kthread+0x116/0x130\n[  226.060661]  ? kthread_flush_work_fn+0x10/0x10\n[  226.060724]  ret_from_fork+0x35/0x40\n...","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":"xprtrdma: treat all calls not a bcall when bc_serv is NULL","id":"CVE-2022-49321","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":8,"next":{"headline":"tracing: Fix sleeping function called from invalid context on RT kernel","id":"CVE-2022-49322"},"packages":[],"prev":{"headline":"dmaengine: zynqmp_dma: In struct zynqmp_dma_chan fix desc_size data type","id":"CVE-2022-49320"},"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":"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 null pointer dereference in the Linux kernel's xprtrdma module allows a remote attacker to cause a system crash via a malformed RPC reply.","url":"https://insights.sbomify.com/CVE-2022-49321/"}
