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-2023-53082 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-2023-53082/ (Markdown: https://insights.sbomify.com/CVE-2023-53082/index.md)","id":"CVE-2023-53082","markdown":"https://insights.sbomify.com/CVE-2023-53082/index.md","name":"CVE-2023-53082","record":{"aliases":["BELL-CVE-2023-53082","DEBIAN-CVE-2023-53082","GHSA-4534-9h9q-hvrh","UBUNTU-CVE-2023-53082"],"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 use-after-free vulnerability in the Linux kernel's vp_vdpa driver causes a kernel panic during device hot unplug, leading to denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nvp_vdpa: fix the crash in hot unplug with vp_vdpa\n\nWhile unplugging the vp_vdpa device, it triggers a kernel panic\nThe root cause is: vdpa_mgmtdev_unregister() will accesses modern\ndevices which will cause a use after free.\nSo need to change the sequence in vp_vdpa_remove\n\n[  195.003359] BUG: unable to handle page fault for address: ff4e8beb80199014\n[  195.004012] #PF: supervisor read access in kernel mode\n[  195.004486] #PF: error_code(0x0000) - not-present page\n[  195.004960] PGD 100000067 P4D 1001b6067 PUD 1001b7067 PMD 1001b8067 PTE 0\n[  195.005578] Oops: 0000 1 PREEMPT SMP PTI\n[  195.005968] CPU: 13 PID: 164 Comm: kworker/u56:10 Kdump: loaded Not tainted 5.14.0-252.el9.x86_64 #1\n[  195.006792] Hardware name: Red Hat KVM/RHEL, BIOS edk2-20221207gitfff6d81270b5-2.el9 unknown\n[  195.007556] Workqueue: kacpi_hotplug acpi_hotplug_work_fn\n[  195.008059] RIP: 0010:ioread8+0x31/0x80\n[  195.008418] Code: 77 28 48 81 ff 00 00 01 00 76 0b 89 fa ec 0f b6 c0 c3 cc cc cc cc 8b 15 ad 72 93 01 b8 ff 00 00 00 85 d2 75 0f c3 cc cc cc cc \u003c8a\u003e 07 0f b6 c0 c3 cc cc cc cc 83 ea 01 48 83 ec 08 48 89 fe 48 c7\n[  195.010104] RSP: 0018:ff4e8beb8067bab8 EFLAGS: 00010292\n[  195.010584] RAX: ffffffffc05834a0 RBX: ffffffffc05843c0 RCX: ff4e8beb8067bae0\n[  195.011233] RDX: ff1bcbd580f88000 RSI: 0000000000000246 RDI: ff4e8beb80199014\n[  195.011881] RBP: ff1bcbd587e39000 R08: ffffffff916fa2d0 R09: ff4e8beb8067ba68\n[  195.012527] R10: 000000000000001c R11: 0000000000000000 R12: ff1bcbd5a3de9120\n[  195.013179] R13: ffffffffc062d000 R14: 0000000000000080 R15: ff1bcbe402bc7805\n[  195.013826] FS:  0000000000000000(0000) GS:ff1bcbe402740000(0000) knlGS:0000000000000000\n[  195.014564] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[  195.015093] CR2: ff4e8beb80199014 CR3: 0000000107dea002 CR4: 0000000000771ee0\n[  195.015741] PKRU: 55555554\n[  195.016001] Call Trace:\n[  195.016233]  \u003cTASK\u003e\n[  195.016434]  vp_modern_get_status+0x12/0x20\n[  195.016823]  vp_vdpa_reset+0x1b/0x50 [vp_vdpa]\n[  195.017238]  virtio_vdpa_reset+0x3c/0x48 [virtio_vdpa]\n[  195.017709]  remove_vq_common+0x1f/0x3a0 [virtio_net]\n[  195.018178]  virtnet_remove+0x5d/0x70 [virtio_net]\n[  195.018618]  virtio_dev_remove+0x3d/0x90\n[  195.018986]  device_release_driver_internal+0x1aa/0x230\n[  195.019466]  bus_remove_device+0xd8/0x150\n[  195.019841]  device_del+0x18b/0x3f0\n[  195.020167]  ?
