Vulnerability from github – Published: 2024-05-21 18:31 – Updated: 2025-03-06 15:34

Details

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

thermal: intel: powerclamp: fix mismatch in get function for max_idle

KASAN reported this

  [ 444.853098] BUG: KASAN: global-out-of-bounds in param_get_int+0x77/0x90
  [ 444.853111] Read of size 4 at addr ffffffffc16c9220 by task cat/2105
  ...
  [ 444.853442] The buggy address belongs to the variable:
  [ 444.853443] max_idle+0x0/0xffffffffffffcde0 [intel_powerclamp]

There is a mismatch between the param_get_int and the definition of max_idle. Replacing param_get_int with param_get_byte resolves this issue.

Severity

7.1 (High)

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.
