Technical description

In the Linux kernel, the following vulnerability has been resolved:

ata: sata_dwc_460ex: Fix crash due to OOB write

the driver uses libata's "tag" values from in various arrays.

Since the mentioned patch bumped the ATA_TAG_INTERNAL to 32,

the value of the SATA_DWC_QCMD_MAX needs to account for that.

Otherwise ATA_TAG_INTERNAL usage cause similar crashes like
