delivered to AMD 10GbE NICs on internet-facing servers; a remote attacker\\u2019s packets reach this path after routing without needing local access.\\nAC:H - The fix and commit message attribute the underflow to intermittent hardware descriptor inconsistencies (PL vs. accumulated buffer lengths) that the attacker cannot reliably force, matching CVSS conditions beyond attacker control.\\nPR:N - Triggering the RX path requires only sending frames to the interface; no authentication, local account, or capability is needed.\\nUI:N - Exploitation needs no victim action such as mounting a device or opening a file; traffic received by the NIC is sufficient.\\nS:U - Impact stays within the host kernel\\u2019s security authority (crash/memory corruption in the driver/stack); it does not cross a VM, IOMMU, or other security boundary.\\nC:H - When buf2_len underflows or exceeds the DMA buffer, skb_add_rx_frag installs an oversized frag, enabling out-of-bounds reads of adjacent memory when the skb is processed.\\nI:H - The same length underflow corrupts skb-\u003elen/data_len and frag metadata before the BUG_ON, yielding memory corruption that can be leveraged toward control-flow or further write primitives, consistent with similar ethernet underflow scorings.\\nA:H - The bad skb lengths trigger BUG_ON(skb-\u003elen \u003c skb-\u003edata_len) in skbuff.h (e.g. via skb_pull in eth_type_trans), causing an intermittent kernel panic as described in the fix.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\":
