CVE-2025-21820

CVE-2025-21820 affects the Linux kernel tty/xilinx_uartps driver. A deadlock could occur due to a circular lock dependency between uart_port_lock and console_lock when handling sysrq. The fix splits sysrq handling into two parts: using a prepare step under the port lock and deferring actual handl...
