Описание

Оригинално описание

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 [1] unreferenced object 0xffff888113c6cdc0 (size 224): ... backtrace (crc be3d3fda): kmem_cache_alloc_node_noprof+0x3b1/0x410 __alloc_skb+0xde/0x830 igc_fpe_xmit_smd_frame.isra.0+0xad/0x1b0 igc_fpe_send_mpacket+0x37/0x90 ethtool_mmsv_verify_timer+0x15e/0x300
