In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Serialize flash version read in reset handler
The "update cache versions without reset" sysfs reset operation (0x20261)
calls get_flash_version(), which reads hardware flash registers, without
holding ha->optrom_mutex. The VPD update path serializes the same call
under optrom_mutex, so this reset path can interleave its flash register
accesses with a concurrent VPD or optrom flash operation and corrupt the
reads.
Hold ha->optrom_mutex across the get_flash_version() call to match the
VPD update path.
