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...

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

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-2026-53073

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...
