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.
