  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Serialize flash version read in reset handler\n\nThe \"update cache versions without reset\" sysfs reset operation (0x20261)\ncalls get_flash_version(), which reads hardware flash registers, without\nholding ha->optrom_mutex. The VPD update path serializes the same call\nunder optrom_mutex, so this reset path can interleave its flash register\naccesses with a concurrent VPD or optrom flash operation and corrupt the\nreads.\n\nHold ha->optrom_mutex across the get_flash_version() call to match the\nVPD update path.",
