Vulnerability from fkie_nvd - Published: 2026-07-19 16:17 - Updated: 2026-10-19 21:17

Severity

9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: ixgbevf: fix use-after-free in VEPA multicast source pruning ixgbevf_clean_rx_irq() prunes frames whose source MAC matches the VF's own address (VEPA multicast workaround) by freeing the skb and continuing to the next descriptor: dev_kfree_skb_irq(skb); continue; The skb pointer is declared outside the while loop and persists across iterations. Because the continue skips the "skb = NULL" reset at the bottom of the loop, the next iteration enters the "else if (skb)" path and calls ixgbevf_add_rx_frag() on the freed skb, dereferencing skb_shinfo(skb)->nr_frags - a use-after-free in NAPI softirq context. The sibling driver iavf already handles this correctly by nulling the pointer before continuing. Apply the same pattern here. I do not have ixgbevf hardware; the bug was found by static analysis (scan_drop_continue_loops.py + semgrep drop_continue_in_loop, multi-tool corroboration with the highest score in the scan). The UAF was confirmed under KASAN by loading a test module that reproduces the exact code pattern (alloc skb, kfree_skb, then read skb_shinfo(skb)->nr_frags): BUG: KASAN: slab-use-after-free in ixgbevf_uaf_test_init+0x100/0x1000 Read of size 8 at addr 000000006163ae78 by task insmod/30 freed 208-byte region [000000006163adc0, 000000006163ae90) QEMU emulates igb (82576) but not ixgbe (82599), and the igbvf VF driver does not include the VEPA source pruning path, so a full end-to-end reproduction with emulated hardware was not possible.

Because the continue skips the \"skb = NULL\" reset at the\nbottom of the loop, the next iteration enters the \"else if (skb)\" path\nand calls ixgbevf_add_rx_frag() on the freed skb, dereferencing\nskb_shinfo(skb)-\u003enr_frags - a use-after-free in NAPI softirq context.\n\nThe sibling driver iavf already handles this correctly by nulling the\npointer before continuing.  Apply the same pattern here.\n\nI do not have ixgbevf hardware; the bug was found by static analysis\n(scan_drop_continue_loops.py + semgrep drop_continue_in_loop, multi-tool\ncorroboration with the highest score in the scan).  The UAF was confirmed\nunder KASAN by loading a test module that reproduces the exact code\npattern (alloc skb, kfree_skb, then read skb_shinfo(skb)-\u003enr_frags):\n\n  BUG: KASAN: slab-use-after-free in ixgbevf_uaf_test_init+0x100/0x1000\n  Read of size 8 at addr 000000006163ae78 by task insmod/30\n  freed 208-byte region [000000006163adc0, 000000006163ae90)\n\nQEMU emulates igb (82576) but not ixgbe (82599), and the igbvf VF\ndriver does not include the VEPA source pruning path, so a full\nend-to-end reproduction with emulated hardware was not possible."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
