  "details": "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-\u003eoptrom_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-\u003eoptrom_mutex across the get_flash_version() call to match the VPD update path.",
