Description OSIDB Bzimport 2026-09-17 18:12:20 UTC 
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.
