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-2022-49976 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-2022-49976/ (Markdown: https://insights.sbomify.com/CVE-2022-49976/index.md)","id":"CVE-2022-49976","markdown":"https://insights.sbomify.com/CVE-2022-49976/index.md","name":"CVE-2022-49976","record":{"aliases":["DEBIAN-CVE-2022-49976","GHSA-2cr7-6fpw-9hfx","UBUNTU-CVE-2022-49976"],"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":"low_privilege","summary":"A bug in the x86-android-tablets kernel driver causes a system crash when running on devices with Windows BIOS, leading to denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86: x86-android-tablets: Fix broken touchscreen on Chuwi Hi8 with Windows BIOS\n\nThe x86-android-tablets handling for the Chuwi Hi8 is only necessary with\nthe Android BIOS and it is causing problems with the Windows BIOS version.\n\nSpecifically when trying to register the already present touchscreen\nx86_acpi_irq_helper_get() calls acpi_unregister_gsi(), this breaks\nthe working of the touchscreen and also leads to an oops:\n\n[   14.248946] ------------[ cut here ]------------\n[   14.248954] remove_proc_entry: removing non-empty directory 'irq/75', leaking at least 'MSSL0001:00'\n[   14.248983] WARNING: CPU: 3 PID: 440 at fs/proc/generic.c:718 remove_proc_entry\n...\n[   14.249293]  unregister_irq_proc+0xe0/0x100\n[   14.249305]  free_desc+0x29/0x70\n[   14.249312]  irq_free_descs+0x4b/0x80\n[   14.249320]  mp_unmap_irq+0x5c/0x60\n[   14.249329]  acpi_unregister_gsi_ioapic+0x2a/0x40\n[   14.249338]  x86_acpi_irq_helper_get+0x4b/0x190 [x86_android_tablets]\n[   14.249355]  x86_android_tablet_init+0x178/0xe34 [x86_android_tablets]\n\nAdd an init callback for the Chuwi Hi8, which detects when the Windows BIOS\nis in use and exits with -ENODEV in that case, fixing this.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"platform/x86: x86-android-tablets: Fix broken touchscreen on Chuwi Hi8 with Windows BIOS","id":"CVE-2022-49976","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"null_dereference","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"ftrace: Fix NULL pointer dereference in is_ftrace_trampoline when ftrace is dead","id":"CVE-2022-49977"},"packages":[],"prev":{"headline":"bpf: Don't redirect packets with invalid pkt_len","id":"CVE-2022-49975"},"products":["Linux"],"published":"2025-06-18","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A bug in the x86-android-tablets kernel driver causes a system crash when running on devices with Windows BIOS, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2022-49976/"}
