Detailsinfo

A vulnerability was found in Linux Kernel up to 5.10.179/5.15.110/6.1.27/6.2.14/6.3.1 and classified as critical. Affected by this issue is some unknown functionality of the component imx. Using CWE to declare the problem leads to CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: spi: imx: 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.
