CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's pch_uart driver, where a failure to check the result of the dma_alloc_coherent() function could lead to a NULL pointer dereference in dma_handle_rx(). This flaw could potentially disrupt system stability and performance by causing crashes or undefined behavior. Organizations using affected Linux systems, particularly those relying on serial communication, should prioritize applying the patch to mitigate risks associated with this issue.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: tty: serial: pch_uart: add check for dma_alloc_coherent() Add a check for dma_alloc_coherent() failure to prevent a potential NULL pointer dereference in dma_handle_rx(). Properly release DMA channels and the PCI device reference using a goto ladder if the allocation fails.
