CVE-2022-50824 (GCVE-0-2022-50824)

Vulnerability from cvelistv5 – Published: 2025-12-30 12:08 – Updated: 2026-05-11 19:25

Title

tpm: tpm_tis: Add the missed acpi_put_table() to fix memory leak

Summary

In the Linux kernel, the following vulnerability has been resolved: tpm: tpm_tis: Add the missed acpi_put_table() to fix memory leak In check_acpi_tpm2(), we get the TPM2 table just to make sure the table is there, not used after the init, so the acpi_put_table() should be added to release the ACPI memory.

Severity

No CVSS data available.

Assigner

Linux mitre root

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.
