CVE-2025-71273 Details
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: Use devm_kmemdup() in rtw_set_supported_band() Simplify the code by using device managed memory allocations. This also fixes a memory leak in rtw_register_hw(). The supported bands were not freed in the error path. Copied from commit 145df52a8671 ("wifi: rtw89: Convert rtw89_core_set_supported_band to use devm_*").
A vulnerability in the Linux kernel's WiFi RTW88 driver has been addressed by improving memory management. The issue involved a memory leak in the 'rtw_register_hw()' function, where allocated memory for supported bands was not properly freed in case of an error. The vulnerability has been resolved by modifying the 'rtw_set_supported_band()' function to use device-managed memory allocation, which automatically handles memory cleanup and prevents leaks.
Users can apply the latest updates from the Linux kernel stable tree to address this vulnerability.
