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...

PT-2026-61200

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists in the qcom geni serial driver when uart flush buffer is executed before the DMA completion interrupt request IRQ is delivered. If kfifo reset is called while a D...

SUSE CVE-2026-53073

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcildisc: Clear HCIUARTPROTOINIT on error When hciregisterdev fails in hciuartregisterdev HCIUARTPROTOINIT is not cleared before calling hu-proto-closehu and setting hu-hdev to NULL. This means incoming UART data will...

CVE-2026-10644

The Microchip SERCOM-G1 UART driver drivers/serial/uartmchpsercomg1.c, used by the PIC32CM-JH SoC family, contains an out-of-bounds write in its asynchronous DMA receive path. When uartrxenable is invoked with a one-byte receive buffer len == 1 and CONFIGUARTMCHPASYNC is enabled, the RX-complete...

CVE-2026-38571

The CVE-2026-38571 case concerns the Tenda N300 F3 device (version V603), where the unauthenticated UART debug console stores WPA2 credentials in cleartext and does not require authentication for rr/wr memory read/write commands. This enables a physically proximate attacker to extract stored WPA2...

CVE-2026-10642

The Zephyr PL011 UART driver drivers/serial/uartpl011.c contains an unbounded software loop in pl011irqtxenable that repeatedly invokes the interrupt-driven application callback while the TX interrupt mask bit PL011IMSCTXIM is set, to work around the controller's level-transition TX-interrupt...

CVE-2026-10642 Unbounded TX busy-loop DoS in Zephyr PL011 UART driver under CTS hardware flow control

CVE-2026-10642

The CVE-2026-10642 issue affects the Zephyr PL011 UART driver (drivers/serial/uart_pl011.c) where pl011_irq_tx_enable() can spin in an unbounded loop when CTS hardware flow control is enabled and CTS is de-asserted by the peer. This causes the TX interrupt to remain masked and the controller to s...
