Summary
CVE-2026-23059 affecting package kernel for versions less than 6.6.126.1-1
Details

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

scsi: qla2xxx: Sanitize payload size to prevent member overflow

In qla27xxcopyfpinpkt() and qla27xxcopymultiplepkt(), the framesize 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 purexitem.

If the reported framesize 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 CONFIGFORTIFY_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.
