Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rt2x00: Fix memory leak when handling surveys
When removing a rt2x00 device, its associated channel surveys
are not freed, causing a memory leak observable with kmemleak:
unreferenced object 0xffff9620f0881a00 (size 512):
comm "systemd-udevd", pid 2290, jiffies 4294906974 (age 33.768s)
hex dump (first 32 bytes):

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.
