CVE-2024-40904 describes a CPU lockup vulnerability in the Linux kernel's cdc-wdm USB driver. This occurs due to excessive logging of error messages when the driver repeatedly resubmits interrupt URBs with a -EPROTO status, particularly when combined with dummy-hcd emulation. The vulnerability is rated Medium (CVSS 5.5) with a local attack vector and low attack complexity, leading to high availability impact (CPU lockup). There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this CVE.
