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-2022-48823 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-2022-48823/ (Markdown: https://insights.sbomify.com/CVE-2022-48823/index.md)","id":"CVE-2022-48823","markdown":"https://insights.sbomify.com/CVE-2022-48823/index.md","name":"CVE-2022-48823","record":{"aliases":["DEBIAN-CVE-2022-48823","GHSA-pmvp-cjhm-664w","UBUNTU-CVE-2022-48823"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel SCSI driver","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel qedf SCSI driver causes a hung task and denial of service when a LOGO is received during a task management function.","user_interaction":"not_required","vuln_class":"race_condition"},"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: qedf: Fix refcount issue when LOGO is received during TMF\n\nHung task call trace was seen during LOGO processing.\n\n[  974.309060] [0000:00:00.0]:[qedf_eh_device_reset:868]: 1:0:2:0: LUN RESET Issued...\n[  974.309065] [0000:00:00.0]:[qedf_initiate_tmf:2422]: tm_flags 0x10 sc_cmd 00000000c16b930f op = 0x2a target_id = 0x2 lun=0\n[  974.309178] [0000:00:00.0]:[qedf_initiate_tmf:2431]: portid=016900 tm_flags =LUN RESET\n[  974.309222] [0000:00:00.0]:[qedf_initiate_tmf:2438]: orig io_req = 00000000ec78df8f xid = 0x180 ref_cnt = 1.\n[  974.309625] host1: rport 016900: Received LOGO request while in state Ready\n[  974.309627] host1: rport 016900: Delete port\n[  974.309642] host1: rport 016900: work event 3\n[  974.309644] host1: rport 016900: lld callback ev 3\n[  974.313243] [0000:61:00.2]:[qedf_execute_tmf:2383]:1: fcport is uploading, not executing flush.\n[  974.313295] [0000:61:00.2]:[qedf_execute_tmf:2400]:1: task mgmt command success...\n[  984.031088] INFO: task jbd2/dm-15-8:7645 blocked for more than 120 seconds.\n[  984.031136]       Not tainted 4.18.0-305.el8.x86_64 #1\n\n[  984.031166] \"echo 0 \u003e /proc/sys/kernel/hung_task_timeout_secs\" disables this message.\n[  984.031209] jbd2/dm-15-8    D    0  7645      2 0x80004080\n[  984.031212] Call Trace:\n[  984.031222]  __schedule+0x2c4/0x700\n[  984.031230]  ? unfreeze_partials.isra.83+0x16e/0x1a0\n[  984.031233]  ? bit_wait_timeout+0x90/0x90\n[  984.031235]  schedule+0x38/0xa0\n[  984.031238]  io_schedule+0x12/0x40\n[  984.031240]  bit_wait_io+0xd/0x50\n[  984.031243]  __wait_on_bit+0x6c/0x80\n[  984.031248]  ? free_buffer_head+0x21/0x50\n[  984.031251]  out_of_line_wait_on_bit+0x91/0xb0\n[  984.031257]  ? init_wait_var_entry+0x50/0x50\n[  984.031268]  jbd2_journal_commit_transaction+0x112e/0x19f0 [jbd2]\n[  984.031280]  kjournald2+0xbd/0x270 [jbd2]\n[  984.031284]  ? finish_wait+0x80/0x80\n[  984.031291]  ? commit_timeout+0x10/0x10 [jbd2]\n[  984.031294]  kthread+0x116/0x130\n[  984.031300]  ? kthread_flush_work_fn+0x10/0x10\n[  984.031305]  ret_from_fork+0x1f/0x40\n\nThere was a ref count issue when LOGO is received during TMF.
