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-2022-50423 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-2022-50423/ (Markdown: https://insights.sbomify.com/CVE-2022-50423/index.md)","id":"CVE-2022-50423","markdown":"https://insights.sbomify.com/CVE-2022-50423/index.md","name":"CVE-2022-50423","record":{"aliases":["DEBIAN-CVE-2022-50423","GHSA-mrmc-2f6j-hcp2","UBUNTU-CVE-2022-50423"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","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 ACPICA component allows attackers to cause a denial of service or potentially execute arbitrary code.","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":"cna","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\nACPICA: Fix use-after-free in acpi_ut_copy_ipackage_to_ipackage()\n\nThere is an use-after-free reported by KASAN:\n\n  BUG: KASAN: use-after-free in acpi_ut_remove_reference+0x3b/0x82\n  Read of size 1 at addr ffff888112afc460 by task modprobe/2111\n  CPU: 0 PID: 2111 Comm: modprobe Not tainted 6.1.0-rc7-dirty\n  Hardware name: QEMU Standard PC (i440FX + PIIX, 1996),\n  Call Trace:\n   \u003cTASK\u003e\n   kasan_report+0xae/0xe0\n   acpi_ut_remove_reference+0x3b/0x82\n   acpi_ut_copy_iobject_to_iobject+0x3be/0x3d5\n   acpi_ds_store_object_to_local+0x15d/0x3a0\n   acpi_ex_store+0x78d/0x7fd\n   acpi_ex_opcode_1A_1T_1R+0xbe4/0xf9b\n   acpi_ps_parse_aml+0x217/0x8d5\n   ...\n   \u003c/TASK\u003e\n\nThe root cause of the problem is that the acpi_operand_object\nis freed when acpi_ut_walk_package_tree() fails in\nacpi_ut_copy_ipackage_to_ipackage(), lead to repeated release in\nacpi_ut_copy_iobject_to_iobject().
