Doc Text:	A flaw was found in the Linux kernel's `scsi: qla2xxx` component. A redundant read of the Vital Product Data (VPD) flash in the `qla2x00_sysfs_read_vpd()` function occurs without the necessary locking mechanism. This exposes flash access to concurrent operations, which can lead to unpredictable behavior or data integrity issues within the system.	Story Points:	---

Description OSIDB Bzimport 2026-09-17 17:45:06 UTC

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

scsi: qla2xxx: Remove redundant VPD flash read in sysfs read path

qla2x00_sysfs_read_vpd() called ha->isp_ops->read_optrom() a second time
after releasing optrom_mutex. The repeated read is redundant and, unlike
the first, runs without optrom_mutex held, exposing flash access to
concurrent optrom operations. Drop the duplicate call.
