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-2026-43311 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-2026-43311/ (Markdown: https://insights.sbomify.com/CVE-2026-43311/index.md)","id":"CVE-2026-43311","markdown":"https://insights.sbomify.com/CVE-2026-43311/index.md","name":"CVE-2026-43311","record":{"aliases":["AZL-86199","BELL-CVE-2026-43311","DEBIAN-CVE-2026-43311","GHSA-5vxj-rjpg-8mhr","ROOT-OS-DEBIAN-13-CVE-2026-43311","ROOT-OS-UBUNTU-2204-CVE-2026-43311","ROOT-OS-UBUNTU-2404-CVE-2026-43311","UBUNTU-CVE-2026-43311"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"An unsafe function call during system resume on Tegra platforms can trigger a kernel warning, potentially leading to system instability or denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"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\nsoc/tegra: pmc: Fix unsafe generic_handle_irq() call\n\nCurrently, when resuming from system suspend on Tegra platforms,\nthe following warning is observed:\n\nWARNING: CPU: 0 PID: 14459 at kernel/irq/irqdesc.c:666\nCall trace:\n handle_irq_desc+0x20/0x58 (P)\n tegra186_pmc_wake_syscore_resume+0xe4/0x15c\n syscore_resume+0x3c/0xb8\n suspend_devices_and_enter+0x510/0x540\n pm_suspend+0x16c/0x1d8\n\nThe warning occurs because generic_handle_irq() is being called from\na non-interrupt context which is considered as unsafe.\n\nFix this warning by deferring generic_handle_irq() call to an IRQ work\nwhich gets executed in hard IRQ context where generic_handle_irq()\ncan be called safely.\n\nWhen PREEMPT_RT kernels are used, regular IRQ work (initialized with\ninit_irq_work) is deferred to run in per-CPU kthreads in preemptible\ncontext rather than hard IRQ context.
