No real init-namespace administrative capability is required for the read-side race.\nUI:N - Exploitation does not require a victim user to open a file or perform another action; the attacker directly accesses the local IIO interfaces.\nS:U - The issue corrupts or misuses kernel objects within the same kernel security authority. It does not cross a VM, IOMMU, or other separate security scope boundary.\nC:H - The old ordering can leave userspace-visible IIO attributes and file operations pointing at freed or partially initialized buffer/trigger state. This use-after-free class can be leveraged for kernel memory disclosure, so confidentiality impact is High.\nI:H - The dangling IIO buffer state includes function-pointer-bearing access structures and kernel object pointers reachable from callbacks. A use-after-free in this context is defensibly exploitable for control-flow hijack or arbitrary kernel memory modification.\nA:H - Even without full exploitation, racing these callbacks against probe or removal can dereference invalid or freed kernel objects and crash or hang the kernel." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
