CVE-2026-74655

CVE-2026-74655 is a Denial of Service flaw in the Linux kernel's qcom-geni UART driver (DMA-mode). The root cause is a missing flush_buffer callback in the DMA-mode uart_ops: when TCOFLUSH is issued during an in-flight TX DMA transfer, the transfer can complete after the serial core resets the tr...
