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-2023-53644 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-2023-53644/ (Markdown: https://insights.sbomify.com/CVE-2023-53644/index.md)","id":"CVE-2023-53644","markdown":"https://insights.sbomify.com/CVE-2023-53644/index.md","name":"CVE-2023-53644","record":{"aliases":["BELL-CVE-2023-53644","DEBIAN-CVE-2023-53644","GHSA-hcvh-9qhf-6r43","UBUNTU-CVE-2023-53644"],"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 missing endpoint check in the radio-shark2 USB driver allows a local attacker to trigger a kernel warning and potential 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\nmedia: radio-shark: Add endpoint checks\n\nThe syzbot fuzzer was able to provoke a WARNING from the radio-shark2\ndriver:\n\n------------[ cut here ]------------\nusb 1-1: BOGUS urb xfer, pipe 1 != type 3\nWARNING: CPU: 0 PID: 3271 at drivers/usb/core/urb.c:504 usb_submit_urb+0xed2/0x1880 drivers/usb/core/urb.c:504\nModules linked in:\nCPU: 0 PID: 3271 Comm: kworker/0:3 Not tainted 6.1.0-rc4-syzkaller #0\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 10/26/2022\nWorkqueue: usb_hub_wq hub_event\nRIP: 0010:usb_submit_urb+0xed2/0x1880 drivers/usb/core/urb.c:504\nCode: 7c 24 18 e8 00 36 ea fb 48 8b 7c 24 18 e8 36 1c 02 ff 41 89 d8 44 89 e1 4c 89 ea 48 89 c6 48 c7 c7 a0 b6 90 8a e8 9a 29 b8 03 \u003c0f\u003e 0b e9 58 f8 ff ff e8 d2 35 ea fb 48 81 c5 c0 05 00 00 e9 84 f7\nRSP: 0018:ffffc90003876dd0 EFLAGS: 00010282\nRAX: 0000000000000000 RBX: 0000000000000003 RCX: 0000000000000000\nRDX: ffff8880750b0040 RSI: ffffffff816152b8 RDI: fffff5200070edac\nRBP: ffff8880172d81e0 R08: 0000000000000005 R09: 0000000000000000\nR10: 0000000080000000 R11: 0000000000000000 R12: 0000000000000001\nR13: ffff8880285c5040 R14: 0000000000000002 R15: ffff888017158200\nFS:  0000000000000000(0000) GS:ffff8880b9a00000(0000) knlGS:0000000000000000\nCS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 00007ffe03235b90 CR3: 000000000bc8e000 CR4: 00000000003506f0\nDR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\nDR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\nCall Trace:\n \u003cTASK\u003e\n usb_start_wait_urb+0x101/0x4b0 drivers/usb/core/message.c:58\n usb_bulk_msg+0x226/0x550 drivers/usb/core/message.c:387\n shark_write_reg+0x1ff/0x2e0 drivers/media/radio/radio-shark2.c:88\n...\n\nThe problem was caused by the fact that the driver does not check\nwhether the endpoints it uses are actually present and have the\nappropriate types.
