- Summary
- igc: set tx buffer type for SMD frames
- Details
-
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.
