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-2025-37923 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-2025-37923/ (Markdown: https://insights.sbomify.com/CVE-2025-37923/index.md)","id":"CVE-2025-37923","markdown":"https://insights.sbomify.com/CVE-2025-37923/index.md","name":"CVE-2025-37923","record":{"aliases":["BELL-CVE-2025-37923","DEBIAN-CVE-2025-37923","GHSA-g586-9cjh-f4c9","ROOT-OS-DEBIAN-11-CVE-2025-37923","ROOT-OS-DEBIAN-12-CVE-2025-37923","ROOT-OS-UBUNTU-2204-CVE-2025-37923","ROOT-OS-UBUNTU-2404-CVE-2025-37923","UBUNTU-CVE-2025-37923"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A local attacker can trigger an out-of-bounds write in the Linux kernel tracing subsystem, potentially leading to code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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":"cna","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-787","name":"Out-of-bounds Write"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ntracing: Fix oob write in trace_seq_to_buffer()\n\nsyzbot reported this bug:\n==================================================================\nBUG: KASAN: slab-out-of-bounds in trace_seq_to_buffer kernel/trace/trace.c:1830 [inline]\nBUG: KASAN: slab-out-of-bounds in tracing_splice_read_pipe+0x6be/0xdd0 kernel/trace/trace.c:6822\nWrite of size 4507 at addr ffff888032b6b000 by task syz.2.320/7260\n\nCPU: 1 UID: 0 PID: 7260 Comm: syz.2.320 Not tainted 6.15.0-rc1-syzkaller-00301-g3bde70a2c827 #0 PREEMPT(full)\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 02/12/2025\nCall Trace:\n \u003cTASK\u003e\n __dump_stack lib/dump_stack.c:94 [inline]\n dump_stack_lvl+0x116/0x1f0 lib/dump_stack.c:120\n print_address_description mm/kasan/report.c:408 [inline]\n print_report+0xc3/0x670 mm/kasan/report.c:521\n kasan_report+0xe0/0x110 mm/kasan/report.c:634\n check_region_inline mm/kasan/generic.c:183 [inline]\n kasan_check_range+0xef/0x1a0 mm/kasan/generic.c:189\n __asan_memcpy+0x3c/0x60 mm/kasan/shadow.c:106\n trace_seq_to_buffer kernel/trace/trace.c:1830 [inline]\n tracing_splice_read_pipe+0x6be/0xdd0 kernel/trace/trace.c:6822\n ....\n==================================================================\n\nIt has been reported that trace_seq_to_buffer() tries to copy more data\nthan PAGE_SIZE to buf.
