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-2025-71195 in the wild and no public exploit code.\n\nAffected product: 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-2025-71195/ (Markdown: https://insights.sbomify.com/CVE-2025-71195/index.md)","id":"CVE-2025-71195","markdown":"https://insights.sbomify.com/CVE-2025-71195/index.md","name":"CVE-2025-71195","record":{"aliases":["BELL-CVE-2025-71195","DEBIAN-CVE-2025-71195","GHSA-h592-q89w-8q5r","ROOT-OS-UBUNTU-2204-CVE-2025-71195","ROOT-OS-UBUNTU-2404-CVE-2025-71195","UBUNTU-CVE-2025-71195"],"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 local attacker can cause a kernel segmentation fault and system crash by reading Xilinx DMA registers via debugfs due to incorrect register bounds.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndmaengine: xilinx: xdma: Fix regmap max_register\n\nThe max_register field is assigned the size of the register memory\nregion instead of the offset of the last register.\nThe result is that reading from the regmap via debugfs can cause\na segmentation fault:\n\ntail /sys/kernel/debug/regmap/xdma.1.auto/registers\nUnable to handle kernel paging request at virtual address ffff800082f70000\nMem abort info:\n  ESR = 0x0000000096000007\n  EC = 0x25: DABT (current EL), IL = 32 bits\n  SET = 0, FnV = 0\n  EA = 0, S1PTW = 0\n  FSC = 0x07: level 3 translation fault\n[...]\nCall trace:\n regmap_mmio_read32le+0x10/0x30\n _regmap_bus_reg_read+0x74/0xc0\n _regmap_read+0x68/0x198\n regmap_read+0x54/0x88\n regmap_read_debugfs+0x140/0x380\n regmap_map_read_file+0x30/0x48\n full_proxy_read+0x68/0xc8\n vfs_read+0xcc/0x310\n ksys_read+0x7c/0x120\n __arm64_sys_read+0x24/0x40\n invoke_syscall.constprop.0+0x64/0x108\n do_el0_svc+0xb0/0xd8\n el0_svc+0x38/0x130\n el0t_64_sync_handler+0x120/0x138\n el0t_64_sync+0x194/0x198\nCode: aa1e03e9 d503201f f9400000 8b214000 (b9400000)\n---[ end trace 0000000000000000 ]---\nnote: tail[1217] exited with irqs disabled\nnote: tail[1217] exited with preempt_count 1\nSegmentation fault","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":"dmaengine: xilinx: xdma: Fix regmap max_register","id":"CVE-2025-71195","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"phy: stm32-usphyc: Fix off by one in probe()","id":"CVE-2025-71196"},"packages":[],"prev":{"headline":"btrfs: fix deadlock in wait_current_trans() due to ignored transaction type","id":"CVE-2025-71194"},"products":["Linux"],"published":"2026-02-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A local attacker can cause a kernel segmentation fault and system crash by reading Xilinx DMA registers via debugfs due to incorrect register bounds.","url":"https://insights.sbomify.com/CVE-2025-71195/"}
