Published May 6, 2026 CVSS 3.1 · 5.5 Medium EPSS < 1% KEV · Not listed
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_*").
