Vulnerability from fkie_nvd - Published: 2024-05-21 16:15 - Updated: 2026-06-17 06:43
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
fbdev: imsttfb: fix a resource leak in probe
I've re-written the error handling but the bug is that if init_imstt()
fails we need to call iounmap(par->cmap_regs).

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.
