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-2023-53524 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-2023-53524/ (Markdown: https://insights.sbomify.com/CVE-2023-53524/index.md)","id":"CVE-2023-53524","markdown":"https://insights.sbomify.com/CVE-2023-53524/index.md","name":"CVE-2023-53524","record":{"aliases":["BELL-CVE-2023-53524","DEBIAN-CVE-2023-53524","GHSA-pvr4-g739-vh5v","UBUNTU-CVE-2023-53524"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"Integer overflow in iwlwifi debugfs handler allows heap overflow, though exploitation requires debugfs access with 0400 privileges.","user_interaction":"not_required","vuln_class":"integer_overflow"},"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-190","name":"Integer Overflow or Wraparound"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: iwlwifi: pcie: Fix integer overflow in iwl_write_to_user_buf\n\nAn integer overflow occurs in the iwl_write_to_user_buf() function,\nwhich is called by the iwl_dbgfs_monitor_data_read() function.\n\nstatic bool iwl_write_to_user_buf(char __user *user_buf, ssize_t count,\n\t\t\t\t  void *buf, ssize_t *size,\n\t\t\t\t  ssize_t *bytes_copied)\n{\n\tint buf_size_left = count - *bytes_copied;\n\n\tbuf_size_left = buf_size_left - (buf_size_left % sizeof(u32));\n\tif (*size \u003e buf_size_left)\n\t\t*size = buf_size_left;\n\nIf the user passes a SIZE_MAX value to the \"ssize_t count\" parameter,\nthe ssize_t count parameter is assigned to \"int buf_size_left\".\nThen compare \"*size\" with \"buf_size_left\" .
