"value": "AV:A - HSR/PRP is an IEC 62439-3 Layer-2 Ethernet ring protocol; the vulnerable path is the slave rx_handler (hsr_handle_frame → hsr_forward_skb → hsr_deliver_master) and requires the attacker to be on the same LAN/ring segment as the HSR interfaces.\nAC:L - An adjacent attacker can reliably deliver frames addressed to the HSR node (or multicast/broadcast) into the vulnerable deliver path; use-after-free triggering does not depend on conditions outside the attacker's ability to send traffic.\nPR:N - Exploitation is on the unauthenticated packet-receive path of an already-configured HSR device; no credentials or privileges are required of the remote adjacent attacker.\nUI:N - Frames are processed automatically by the kernel HSR rx_handler with no user action required.\nS:U - Impact is confined to the host kernel that runs the HSR stack; there is no cross-authority boundary such as a VM or IOMMU escape.\nC:H - This is a use-after-free on an sk_buff; UAF on freed heap objects can be leveraged for arbitrary kernel memory disclosure.\nI:H - sk_buff use-after-free enables heap reuse/spraying and control-flow hijacking primitives, so integrity impact is High.\nA:H - Use-after-free of an sk_buff can cause kernel oops/panic or otherwise crash the host when the freed object is accessed or corrupted."
