CVE-2025-38656

Severity CVSS v4.0:
Pending analysis
Type:
CWE-416 Use After Free
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: iwlwifi: Fix error code in iwl_op_mode_dvm_start()<br /> <br /> Preserve the error code if iwl_setup_deferred_work() fails. The current<br /> code returns ERR_PTR(0) (which is NULL) on this path. I believe the<br /> missing error code potentially leads to a use after free involving<br /> debugfs.
