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. (NVD)
