Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.15.5-00039-g2fd9ae1b568c

Description A vulnerability in the Linux kernel has been resolved, which was causing a random warning message when the driver loads. The warning log indicates an unexpected gfp value, and the issue is related to the kmalloc function being called with mem flags that include GFP DMA32 flags. The dma alloc coherent function handles DMA memory regions correctly, making GFP DMA32 unnecessary and safely removable.

Recommendations For Linux kernel versions prior to 5.15.5-00039-g2fd9ae1b568c, update to a version that includes the fix for the warning message when the driver loads. As a temporary workaround, consider modifying the pool alloc page function to remove the GFP DMA32 flags from the mem flags passed to kmalloc.
