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-2024-46848 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-2024-46848/ (Markdown: https://insights.sbomify.com/CVE-2024-46848/index.md)","id":"CVE-2024-46848","markdown":"https://insights.sbomify.com/CVE-2024-46848/index.md","name":"CVE-2024-46848","record":{"aliases":["AZL-50004","BELL-CVE-2024-46848","DEBIAN-CVE-2024-46848","GHSA-f8x4-897j-jj7g","ROOT-OS-DEBIAN-11-CVE-2024-46848","ROOT-OS-UBUNTU-2204-CVE-2024-46848","UBUNTU-CVE-2024-46848"],"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":"A flaw in the Linux kernel's Intel Haswell performance monitoring driver can cause an interrupt loop, leading to a 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\nperf/x86/intel: Limit the period on Haswell\n\nRunning the ltp test cve-2015-3290 concurrently reports the following\nwarnings.\n\nperfevents: irq loop stuck!\n  WARNING: CPU: 31 PID: 32438 at arch/x86/events/intel/core.c:3174\n  intel_pmu_handle_irq+0x285/0x370\n  Call Trace:\n   \u003cNMI\u003e\n   ? __warn+0xa4/0x220\n   ? intel_pmu_handle_irq+0x285/0x370\n   ? __report_bug+0x123/0x130\n   ? intel_pmu_handle_irq+0x285/0x370\n   ? __report_bug+0x123/0x130\n   ? intel_pmu_handle_irq+0x285/0x370\n   ? report_bug+0x3e/0xa0\n   ? handle_bug+0x3c/0x70\n   ? exc_invalid_op+0x18/0x50\n   ? asm_exc_invalid_op+0x1a/0x20\n   ? irq_work_claim+0x1e/0x40\n   ? intel_pmu_handle_irq+0x285/0x370\n   perf_event_nmi_handler+0x3d/0x60\n   nmi_handle+0x104/0x330\n\nThanks to Thomas Gleixner's analysis, the issue is caused by the low\ninitial period (1) of the frequency estimation algorithm, which triggers\nthe defects of the HW, specifically erratum HSW11 and HSW143. (For the\ndetails, please refer https://lore.kernel.org/lkml/87plq9l5d2.ffs@tglx/)\n\nThe HSW11 requires a period larger than 100 for the INST_RETIRED.ALL\nevent, but the initial period in the freq mode is 1. The erratum is the\nsame as the BDM11, which has been supported in the kernel. A minimum\nperiod of 128 is enforced as well on HSW.\n\nHSW143 is regarding that the fixed counter 1 may overcount 32 with the\nHyper-Threading is enabled. However, based on the test, the hardware\nhas more issues than it tells. Besides the fixed counter 1, the message\n'interrupt took too long' can be observed on any counter which was armed\nwith a period \u003c 32 and two events expired in the same NMI. A minimum\nperiod of 32 is enforced for the rest of the events.\nThe recommended workaround code of the HSW143 is not implemented.\nBecause it only addresses the issue for the fixed counter. It brings\nextra overhead through extra MSR writing. No related overcounting issue\nhas been reported so far.","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":"perf/x86/intel: Limit the period on Haswell","id":"CVE-2024-46848","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":4,"next":{"headline":"ASoC: meson: axg-card: fix 'use-after-free'","id":"CVE-2024-46849"},"packages":[],"prev":{"headline":"mm: vmalloc: ensure vmap_block is initialised before adding to queue","id":"CVE-2024-46847"},"products":["Linux"],"published":"2024-09-27","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A flaw in the Linux kernel's Intel Haswell performance monitoring driver can cause an interrupt loop, leading to a denial of service.","url":"https://insights.sbomify.com/CVE-2024-46848/"}
