Details

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

net/mlx5: Lag, fix failure to cancel delayed bond work

Commit 0d4e8ed139d8 ("net/mlx5: Lag, avoid lockdep warnings") accidentally removed a call to cancel delayed bond work thus it may cause queued delay to expire and fall on an already destroyed work queue.

Fix by restoring the call cancel_delayed_work_sync() before destroying the workqueue.

This prevents call trace such as this:

Detection rules are retrieved from Rulezet.

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.
