Description
In the Linux kernel, the following vulnerability has been resolved: spi: qup: Don't skip cleanup in remove's error path Returning early in a platform driver's remove callback is wrong. In this case the dma resources are not released in the error path. this is never retried later and so this is a permanent leak. To fix this, only skip hardware disabling if waking the device fails.

Executive Summary

This vulnerability occurs in the Linux kernel's SPI QUP driver where the remove callback of a platform driver returns early on error, causing DMA resources not to be released properly. This results in a permanent resource leak because the cleanup is skipped and not retried later. The fix ensures that hardware disabling is only skipped if waking the device fails, preventing the leak.

Impact Analysis

The vulnerability can lead to a permanent leak of DMA resources in the Linux kernel, which may cause system instability, degraded performance, or resource exhaustion over time if the affected driver is used.
