CVE-2025-21905

wifi: iwlwifi: limit printed string from FW file

State: Published
Severity: 7.1 High
Published: Apr 1, 2025
Updated: May 11, 2026
Reserved: Dec 29, 2024

Description

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

wifi: iwlwifi: limit printed string from FW file

There's no guarantee here that the file is always with a NUL-termination, so reading the string may read beyond the end of the TLV. If that's the last TLV in the file, it can perhaps even read beyond the end of the file buffer.

Fix that by limiting the print format to the size of the buffer we have.
