CVE-2024-27409 is a vulnerability in the Linux kernel's dw-edma HDMA driver, specifically affecting the handling of DMA transfers in remote setups. A race condition can occur if the doorbell register is toggled before a linked list is fully written, as the linked list elements and pointer are not stored in the same memory as the HDMA controller register. This vulnerability has a CVSS score of 5.5 (Medium), indicating a local attack vector with low complexity, requiring local privileges, and potentially leading to a high impact on availability. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
