CVE-2026-64035

In the Linux kernel, the following vulnerability has been resolved:

igc: set tx buffer type for SMD frames

Sashiko pointed out that igc_fpe_init_smd_frame() initializes
igc_tx_buffer fields for an SMD skb, but does not set the buffer type:
https://sashiko.dev/#/patchset/20260415025226.114115-1-kohei%40enjuk.jp

Since igc_tx_buffer entries are reused, a stale XDP or XSK type can
remain and make TX completion use the wrong cleanup path.

Set the buffer type to IGC_TX_BUFFER_TYPE_SKB.
