adjacent protocols.\nAC:L - An unprivileged attacker can reliably trigger the overflow with a simple read on platforms whose OPP/freq table is large enough (e.g. Tegra actmon with 21 states exceeds PAGE_SIZE); no race or uncontrolled victim state is required.\nPR:L - trans_stat is DEVICE_ATTR_RW (0644), so any unprivileged local user can open and read it; no capabilities or root are required for the vulnerable show path.\nUI:N - Exploitation requires only the attacker reading the sysfs attribute; no victim action is needed.\nS:U - Impact is kernel memory corruption/privilege escalation within the same OS security authority; it does not cross VM, IOMMU, or other scope boundaries.\nC:H - Out-of-bounds write past the PAGE_SIZE kvmalloc/sysfs buffer corrupts adjacent kernel heap memory and can be leveraged for information disclosure under the kernel CVSS guidance for memory-corruption bugs.\nI:H - Unbounded sprintf into the fixed PAGE_SIZE show buffer is a kernel heap out-of-bounds write, which is scored High for integrity and can enable control-flow hijacking.\nA:H - Heap corruption from the overflow can cause kernel oops/panic or unstable operation when adjacent objects are later used, so availability impact is High." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
