CVE-2026-63883
A flaw was found in the Linux kernel's qcomgeni serial driver. A race condition can occur when the uartflushbuffer function executes before the Direct Memory Access DMA completion interrupt is processed. This timing issue can lead to a kernel First-In, First-Out kfifo buffer underflow...

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...
