A use-after-free vulnerability exists in the Linux kernel's TI QSPI driver, which can occur if Direct Memory Access (DMA) setup fails during device probing. This flaw can lead to potential exploitation, allowing attackers to manipulate memory and execute arbitrary code, posing a significant risk to system integrity. Organizations utilizing affected Linux systems, particularly those relying on the TI QSPI driver, should prioritize patching this vulnerability to mitigate the associated risks.

Original NVD Description

In the Linux kernel, the following vulnerability has been resolved: spi: ti-qspi: fix use-after-free after DMA setup failure The driver falls back to PIO mode if DMA setup fails during probe. Make sure to clear the DMA channel pointer also if buffer allocation fails to avoid passing a pointer to the released channel to the DMA engine (or trying to free the channel a second time on late probe errors or driver unbind). This issue was flagged by Sashiko when reviewing a devres allocation conversion patch.
