"value": "AV:L - The vulnerable code is the SCSI mid-layer dispatch path (scsi_queue_rq/scsi_dispatch_cmd) on the initiator side, reached only by submitting I/O to a local SCSI device; there is no remote/network trigger.\nAC:L - Exploitation is a cross-CPU UAF race between command completion/device teardown and the trailing atomic_inc; an attacker controlling a removable/hot-pluggable SCSI device can drive both I/O and removal and retry the race repeatedly, so complexity is Low.\nPR:L - Reaching the vulnerable atomic_inc requires a local authenticated user able to submit I/O to (or open) a SCSI device; no elevated capability is needed to dispatch a command down this path.\nUI:N - The bug is triggered by ordinary I/O submission and concurrent device release; no action by a separate victim user is required.\nS:U - The corruption is confined to the kernel's own memory within the same security authority; no VM/IOMMU/sandbox boundary is crossed.\nC:H - The use-after-free operates on a freed scsi_device slab object whose contents an attacker can control via heap grooming, and per UAF scoring guidance such freed-object access is treated as enabling high-impact information disclosure.\nI:H - The atomic_inc is a use-after-free read-modify-write into a freed, potentially attacker-reallocated object, a memory-corruption write primitive that per guidance is scored High.\nA:H - The commit explicitly states the bug causes a kernel panic, and any use-after-free reliably produces a crash/oops."
