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-2022-49063 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2022-49063/ (Markdown: https://insights.sbomify.com/CVE-2022-49063/index.md)","id":"CVE-2022-49063","markdown":"https://insights.sbomify.com/CVE-2022-49063/index.md","name":"CVE-2022-49063","record":{"aliases":["DEBIAN-CVE-2022-49063","GHSA-9hrg-vg64-94qj","ROOT-OS-DEBIAN-11-CVE-2022-49063","ROOT-OS-UBUNTU-2204-CVE-2022-49063","UBUNTU-CVE-2022-49063"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel ice driver allows attackers to cause a denial of service or potentially execute code.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","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\nice: arfs: fix use-after-free when freeing @rx_cpu_rmap\n\nThe CI testing bots triggered the following splat:\n\n[  718.203054] BUG: KASAN: use-after-free in free_irq_cpu_rmap+0x53/0x80\n[  718.206349] Read of size 4 at addr ffff8881bd127e00 by task sh/20834\n[  718.212852] CPU: 28 PID: 20834 Comm: sh Kdump: loaded Tainted: G S      W IOE     5.17.0-rc8_nextqueue-devqueue-02643-g23f3121aca93 #1\n[  718.219695] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0012.070720200218 07/07/2020\n[  718.223418] Call Trace:\n[  718.227139]\n[  718.230783]  dump_stack_lvl+0x33/0x42\n[  718.234431]  print_address_description.constprop.9+0x21/0x170\n[  718.238177]  ? free_irq_cpu_rmap+0x53/0x80\n[  718.241885]  ? free_irq_cpu_rmap+0x53/0x80\n[  718.245539]  kasan_report.cold.18+0x7f/0x11b\n[  718.249197]  ? free_irq_cpu_rmap+0x53/0x80\n[  718.252852]  free_irq_cpu_rmap+0x53/0x80\n[  718.256471]  ice_free_cpu_rx_rmap.part.11+0x37/0x50 [ice]\n[  718.260174]  ice_remove_arfs+0x5f/0x70 [ice]\n[  718.263810]  ice_rebuild_arfs+0x3b/0x70 [ice]\n[  718.267419]  ice_rebuild+0x39c/0xb60 [ice]\n[  718.270974]  ? asm_sysvec_apic_timer_interrupt+0x12/0x20\n[  718.274472]  ? ice_init_phy_user_cfg+0x360/0x360 [ice]\n[  718.278033]  ? delay_tsc+0x4a/0xb0\n[  718.281513]  ? preempt_count_sub+0x14/0xc0\n[  718.284984]  ? delay_tsc+0x8f/0xb0\n[  718.288463]  ice_do_reset+0x92/0xf0 [ice]\n[  718.292014]  ice_pci_err_resume+0x91/0xf0 [ice]\n[  718.295561]  pci_reset_function+0x53/0x80\n\u003c...\u003e\n[  718.393035] Allocated by task 690:\n[  718.433497] Freed by task 20834:\n[  718.495688] Last potentially related work creation:\n[  718.568966] The buggy address belongs to the object at ffff8881bd127e00\n                which belongs to the cache kmalloc-96 of size 96\n[  718.574085] The buggy address is located 0 bytes inside of\n                96-byte region [ffff8881bd127e00, ffff8881bd127e60)\n[  718.579265] The buggy address belongs to the page:\n[  718.598905] Memory state around the buggy address:\n[  718.601809]  ffff8881bd127d00: fa fb fb fb fb fb fb fb fb fb fb fb fc fc fc fc\n[  718.604796]  ffff8881bd127d80: 00 00 00 00 00 00 00 00 00 00 fc fc fc fc fc fc\n[  718.607794] \u003effff8881bd127e00: fa fb fb fb fb fb fb fb fb fb fb fb fc fc fc fc\n[  718.610811]                    ^\n[  718.613819]  ffff8881bd127e80: 00 00 00 00 00 00 00 00 00 00 00 00 fc fc fc fc\n[  718.617107]  ffff8881bd127f00: fa fb fb fb fb fb fb fb fb fb fb fb fc fc fc fc\n\nThis is due to that free_irq_cpu_rmap() is always being called\n*after* (devm_)free_irq() and thus it tries to work with IRQ descs\nalready freed.
