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-2023-53696 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2023-53696/ (Markdown: https://insights.sbomify.com/CVE-2023-53696/index.md)","id":"CVE-2023-53696","markdown":"https://insights.sbomify.com/CVE-2023-53696/index.md","name":"CVE-2023-53696","record":{"aliases":["BELL-CVE-2023-53696","DEBIAN-CVE-2023-53696","GHSA-hh3x-pv67-6v62","ROOT-OS-DEBIAN-11-CVE-2023-53696","UBUNTU-CVE-2023-53696"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A memory leak in the qla2xxx SCSI driver allows local attackers to cause denial of service by exhausting kernel memory during adapter initialization failures.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Fix memory leak in qla2x00_probe_one()\n\nThere is a memory leak reported by kmemleak:\n\n  unreferenced object 0xffffc900003f0000 (size 12288):\n    comm \"modprobe\", pid 19117, jiffies 4299751452 (age 42490.264s)\n    hex dump (first 32 bytes):\n      00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................\n      00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................\n    backtrace:\n      [\u003c00000000629261a8\u003e] __vmalloc_node_range+0xe56/0x1110\n      [\u003c0000000001906886\u003e] __vmalloc_node+0xbd/0x150\n      [\u003c000000005bb4dc34\u003e] vmalloc+0x25/0x30\n      [\u003c00000000a2dc1194\u003e] qla2x00_create_host+0x7a0/0xe30 [qla2xxx]\n      [\u003c0000000062b14b47\u003e] qla2x00_probe_one+0x2eb8/0xd160 [qla2xxx]\n      [\u003c00000000641ccc04\u003e] local_pci_probe+0xeb/0x1a0\n\nThe root cause is traced to an error-handling path in qla2x00_probe_one()\nwhen the adapter \"base_vha\" initialize failed.
