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

iavf: Fix NULL pointer dereference in iavf_get_link_ksettings

Fix possible NULL pointer dereference, due to freeing of adapter->vf_res in iavf_init_get_resources. Previous commit introduced a regression, where receiving IAVF_ERR_ADMIN_QUEUE_NO_WORK from iavf_get_vf_config would free adapter->vf_res. However, netdev is still registered, so ethtool_ops can be called. Calling iavf_get_link_ksettings with no vf_res, will result with: [ 9385.242676] BUG: kernel NULL pointer dereference, address: 0000000000000008 [ 9385.242683] #PF: supervisor read access in kernel mode [ 9385.242686] #PF: error_code(0x0000) - not-present page [ 9385.242690] PGD 0 P4D 0 [ 9385.242696] Oops: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC PTI [ 9385.242701] CPU: 6 PID: 3217 Comm: pmdalinux Kdump: loaded Tainted: G S E 5.18.0-04958-ga54ce3703613-dirty #1 [ 9385.242708] Hardware name: Dell Inc.

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.
