CVE-2026-63883

The CVE relates to the Linux kernel serial driver for Qualcomm GENI: a kfifo underflow race when uart_flush_buffer() runs before the DMA completion IRQ. The race sequence can cause stale DMA data to be submitted due to kfifo_len() being reset to 0 while tx_remaining is nonzero, leading to an inco...
