- Details
-
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
