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-2023-53280 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-2023-53280/ (Markdown: https://insights.sbomify.com/CVE-2023-53280/index.md)","id":"CVE-2023-53280","markdown":"https://insights.sbomify.com/CVE-2023-53280/index.md","name":"CVE-2023-53280","record":{"aliases":["BELL-CVE-2023-53280","DEBIAN-CVE-2023-53280","GHSA-3x66-jhf4-g79q","UBUNTU-CVE-2023-53280"],"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 qla2xxx SCSI driver causes a system crash when a specific error path is triggered during NVMe 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":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\nscsi: qla2xxx: Remove unused nvme_ls_waitq wait queue\n\nSystem crash when qla2x00_start_sp(sp) returns error code EGAIN and wake_up\ngets called for uninitialized wait queue sp-\u003envme_ls_waitq.\n\n    qla2xxx [0000:37:00.1]-2121:5: Returning existing qpair of ffff8ae2c0513400 for idx=0\n    qla2xxx [0000:37:00.1]-700e:5: qla2x00_start_sp failed = 11\n    BUG: unable to handle kernel NULL pointer dereference at 0000000000000000\n    PGD 0 P4D 0\n    Oops: 0000 [#1] SMP NOPTI\n    Hardware name: HPE ProLiant DL360 Gen10/ProLiant DL360 Gen10, BIOS U32 09/03/2021\n    Workqueue: nvme-wq nvme_fc_connect_ctrl_work [nvme_fc]\n    RIP: 0010:__wake_up_common+0x4c/0x190\n    RSP: 0018:ffff95f3e0cb7cd0 EFLAGS: 00010086\n    RAX: 0000000000000000 RBX: ffff8b08d3b26328 RCX: 0000000000000000\n    RDX: 0000000000000001 RSI: 0000000000000003 RDI: ffff8b08d3b26320\n    RBP: 0000000000000001 R08: 0000000000000000 R09: ffffffffffffffe8\n    R10: 0000000000000000 R11: ffff95f3e0cb7a60 R12: ffff95f3e0cb7d20\n    R13: 0000000000000003 R14: 0000000000000000 R15: 0000000000000000\n    FS:  0000000000000000(0000) GS:ffff8b2fdf6c0000(0000) knlGS:0000000000000000\n    CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n    CR2: 0000000000000000 CR3: 0000002f1e410002 CR4: 00000000007706e0\n    DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n    DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n    PKRU: 55555554\n    Call Trace:\n     __wake_up_common_lock+0x7c/0xc0\n     qla_nvme_ls_req+0x355/0x4c0 [qla2xxx]\n     ?
