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-2024-38626 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-2024-38626/ (Markdown: https://insights.sbomify.com/CVE-2024-38626/index.md)","id":"CVE-2024-38626","markdown":"https://insights.sbomify.com/CVE-2024-38626/index.md","name":"CVE-2024-38626","record":{"aliases":["BELL-CVE-2024-38626","GHSA-34cx-q7hf-42vr","UBUNTU-CVE-2024-38626"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel FUSE","requires_auth":"low_privilege","summary":"A logic error in the Linux kernel FUSE subsystem allows a local attacker to trigger a kernel warning and potential denial of service by manipulating request states.","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":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":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nfuse: clear FR_SENT when re-adding requests into pending list\n\nThe following warning was reported by lee bruce:\n\n  ------------[ cut here ]------------\n  WARNING: CPU: 0 PID: 8264 at fs/fuse/dev.c:300\n  fuse_request_end+0x685/0x7e0 fs/fuse/dev.c:300\n  Modules linked in:\n  CPU: 0 PID: 8264 Comm: ab2 Not tainted 6.9.0-rc7\n  Hardware name: QEMU Standard PC (i440FX + PIIX, 1996)\n  RIP: 0010:fuse_request_end+0x685/0x7e0 fs/fuse/dev.c:300\n  ......\n  Call Trace:\n  \u003cTASK\u003e\n  fuse_dev_do_read.constprop.0+0xd36/0x1dd0 fs/fuse/dev.c:1334\n  fuse_dev_read+0x166/0x200 fs/fuse/dev.c:1367\n  call_read_iter include/linux/fs.h:2104 [inline]\n  new_sync_read fs/read_write.c:395 [inline]\n  vfs_read+0x85b/0xba0 fs/read_write.c:476\n  ksys_read+0x12f/0x260 fs/read_write.c:619\n  do_syscall_x64 arch/x86/entry/common.c:52 [inline]\n  do_syscall_64+0xce/0x260 arch/x86/entry/common.c:83\n  entry_SYSCALL_64_after_hwframe+0x77/0x7f\n  ......\n  \u003c/TASK\u003e\n\nThe warning is due to the FUSE_NOTIFY_RESEND notify sent by the write()\nsyscall in the reproducer program and it happens as follows:\n\n(1) calls fuse_dev_read() to read the INIT request\nThe read succeeds.
