CVE-2026-64303

A flaw was found in the Linux kernel's fsl-lpspi driver. This vulnerability occurs when the transmit TX Direct Memory Access DMA channel fails to prepare, but the receive RX DMA channel continues to operate. This can lead to memory corruption or a use-after-free condition, potentially allowing an...
