PT-2026-52101

Name of the Vulnerable Software and Affected Versions Zephyr versions 4.1.0 through 4.4.0 Description The PL011 UART driver in drivers/serial/uart pl011.c contains an unbounded software loop within the pl011 irq tx enable function. This loop repeatedly invokes the interrupt-driven application...

CVE-2022-50625

In the Linux kernel, the following vulnerability has been resolved: serial: amba-pl011: avoid SBSA UART accessing DMACR register Chapter "B Generic UART" in "ARM Server Base System Architecture" 1 documentation describes a generic UART interface. Such generic UART does not support DMA. In current...

CVE-2022-50625

CVE-2022-50625 is a Linux kernel issue where the SBSA UART path could access the DMACR register in the PL011 driver when DMA is used, potentially causing a data abort and guest segfaults in Xen environments. The fix adds a using_rx_dma check in pl011_dma_rx_stop to avoid DMACR access for SBSA UAR...
