Description
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: fw: fix memory leak in debugfs Fix a memory leak that occurs when reading the fw_info file all the way, since we return NULL indicating no more data, but don't free the status tracking object.
A memory leak vulnerability has been identified in the Linux kernel's iwlwifi wireless driver. This issue arises when the fw_info file is read completely. The driver returns NULL to indicate that there is no more data, but fails to free the associated status tracking object, leading to a memory leak. This vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for upgrading the Linux kernel can be found in the official Linux documentation.
