Details

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

net/9p/usbg: fix handling of the failed kzalloc() memory allocation

On the linux-next, next-20241108 vanilla kernel, the coccinelle tool gave the following error report:

./net/9p/trans_usbg.c:912:5-11: ERROR: allocation function on line 911 returns NULL not ERR_PTR on failure

kzalloc() failure is fixed to handle the NULL return case on the memory exhaustion.

Severity

5.5 (Medium)

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.
