CVE-2026-64110

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

igc: fix potential skb leak in igc_fpe_xmit_smd_frame()

When igc_fpe_init_tx_descriptor() fails, no one takes care of an

allocated skb, leaking it. [1]

Use dev_kfree_skb_any() on failure.

Tested on an I226 adapter with the following command, while injecting

faults in igc_fpe_init_tx_descriptor() to trigger the error path.

# ethtool --set-mm $DEV verify-enabled on tx-enabled on pmac-enabled on
