Summary

A memory leak vulnerability was found in the Linux kernel's igc driver for Intel network adapters. The igc_fpe_xmit_smd_frame() function fails to free an allocated skb buffer when igc_fpe_init_tx_descriptor() fails, causing a memory leak.

Risk Assessment

Memory leak can degrade system performance and potentially exhaust memory, leading to system crashes, especially if the error path is triggered frequently.

Recommendation

Apply the Linux kernel patch that adds dev_kfree_skb_any() call on failure in igc_fpe_xmit_smd_frame(). Update the kernel to a version containing the fix.

Original NVD description (English source)

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
