Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Sanitize payload size to prevent member overflow
In qla27xx_copy_fpin_pkt() and qla27xx_copy_multiple_pkt(), the frame_size
reported by firmware is used to calculate the copy length into
item->iocb. However, the iocb member is defined as a fixed-size 64-byte
array within struct purex_item.
If the reported frame_size exceeds 64 bytes, subsequent memcpy calls will
overflow the iocb member boundary. While extra memory might be allocated,
this cross-member write is unsafe and triggers warnings under
CONFIG_FORTIFY_SOURCE.
Fix this by capping total_bytes to the size of the iocb member (64 bytes)
before allocation and copying. This ensures all copies remain within the
bounds of the destination structure member.
