Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
igc: set tx buffer type for SMD frames<br />
<br />
Sashiko pointed out that igc_fpe_init_smd_frame() initializes<br />
igc_tx_buffer fields for an SMD skb, but does not set the buffer type:<br />
https://sashiko.dev/#/patchset/20260415025226.114115-1-kohei%40enjuk.jp<br />
<br />
Since igc_tx_buffer entries are reused, a stale XDP or XSK type can<br />
remain and make TX completion use the wrong cleanup path.<br />
<br />
Set the buffer type to IGC_TX_BUFFER_TYPE_SKB.
