Vulnerability Title
scsi: ufs: core: Validate connected lane counts
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Validate connected lane counts
The connected lane count is used by TX equalization code to index arrays
sized by UFS_MAX_LANES. Reject zero and out-of-range RX or TX lane counts
before they can be propagated.
