CVE-2026-64234

The CVE-2026-64234 issue in the Linux kernel affects the tty: serial: pch_uart path. It fixes a missing check for dma_alloc_coherent() failure, which could cause a NULL pointer dereference in dma_handle_rx(). The fix adds the check and ensures proper release of DMA channels and the PCI device ref...
